Hello Geeks! I hope all are doing great. So today, in this article, we will solve ImportError: Cannot Import Name. But, before that, we understand in which circumstances this error is raised and what are the main reasons for it and then will try to find possible solutions for them. So, Let’s get started.
ImportError occurs when a file cannot load the module, its classes, or methods in a python file. Now, there may be several reasons for this inability to load a module or its classes, such as;
- The imported module is not imported.
- The imported module is not created.
- Module or Class names are misspelled.
- Imported class is unavailable in certain library
- Or, the imported class is in circular dependency.
There may be more scenarios in which the importerror occurs. But in this article, we will only focus on the last one, i.e., The imported class is in a circular dependency.
To learn more about other reasons for the error, you can visit another article by us, i.e., Import-classes-from-another-file-in-python.
Circular Dependency
So, sometimes it happens that we imported two or modules in our file, and their existence depends on each other. In simples words, we can say that circular dependency is a condition in which two or more modules are interdependent. Now, when this happens, neither of the modules can successfully be imported, resulting in the given error. Let’s see an example to get a better understanding of it.
file1.py
from file2 import B
class A:
b_obj = B()
file2.py
from file1 import A
class B:
A_obj = A()
So, now in the above example, we can see that initialization of A_obj depends on file1, and initialization of B_obj depends on file2. Directly, neither of the files can be imported successfully, which leads to ImportError: Cannot Import Name. Let’s see the output of the above code.

ImportError: cannot import name 'A' from partially initialized module 'file1' (most likely due to a circular import) (C:UsersRishav RajDocumentsPythonPoolCircular Dependencyfile1.py)

Solving ImportError: Cannot Import Name
So, if you understood the core reason for the error, it is not difficult to solve the issue, and I guess most of you have already got the answer till now. Yes, the solution to this is that you can only avoid doing that. The above-given code results from a lousy programming approach, and one should avoid doing that. However, you can achieve your goal by maintaining a separate file for initializing the object.
file1.py
file2.py
file3.py
from file1 import A from file2 import B A_obj = A() B_obj = B()
Example 1: ImportError cannot import name in flask
from flask import Flask
app = Flask(__name__)
@app.route("/")
def hello():
return "Hello World!"
if __name__ == "__main__":
app.run(host='0.0.0.0', port=80, debug=True)
Output:
Traceback (most recent call last):
File "test.py", line 1, in <module>
from flask import Flask
File "/home/pi/programs/flask.py", line 1, in <module>
from flask import Flask
ImportError: cannot import name Flask
The above-given error is raised as the flask is not installed in your system. To solve the error, you need to install it first and then import it. To install it, use the following command.
apt-get install python3-flask
Example 2: ImportError cannot import name in imagetk from pil
# create a class called Person
# create init method
# 2 attributes (name, and birthdate)
# create an object from the Person class
from PIL import Image, ImageTK
import datetime
import tkinter as tk
# create frame

# create frame geometry
window.geometry("400x400")
# set title of frame
window.title("Age Calculator App")
# adding labels

name_label.grid(column=0, row=0)
year_label = tk.Label(text="Year")
year_label.grid(column = 0, row = 1)
month_label = tk.Label(text="Month")
month_label.grid(column = 0, row = 2)
day_label = tk.Label(text="Day")
day_label.grid(column = 0, row = 3)
# adding entries
name_entry = tk.Entry()

year_entry.grid(column=1, row=1)
month_entry = tk.Entry()
month_entry.grid(column=1, row=2)
day_entry = tk.Entry()
day_entry.grid(column=1, row=3)
def calculate_age():
year = int(year_entry.get())
month = int(month_entry.get())
day = int(day_entry.get())
name = name_entry.get()
person = Person(name, datetime.date(year, month, day))
text_answer = tk.Text(master=window, wrap=tk.WORD, height=20, width=30)
text_answer.grid(column= 1, row= 5)
answer = "{name} is {age} years old!".format(name=person.name, age=person.age())
is_old_answer = " Wow you are getting old aren't you?"
text_answer.insert(tk.END, answer)
if person.age() >= 50:
text_answer.insert(tk.END, is_old_answer)
calculate_button = tk.Button(text="Calculate Age!", command=calculate_age)
calculate_button.grid(column=1, row=4)
class Person:
def __init__(self, name, birthdate):
self.name = name
self.birthdate = birthdate
def age(self):
today = datetime.date.today()
age = today.year - self.birthdate.year
return age
image = Image.open('LockVectorDaily.jpg')
image.thumbnail((100, 100), Image.ANTIALIAS)
photo = tk.PhotoImage(file=image)
label_image = tk.Label(image=image)
label_image.grid(column=1, row=0)
window.mainloop()
Output:
from PIL import Image, ImageTK
ImportError: cannot import name 'ImageTK'
Here, the error occurs as Python is unable to import ImageTK. Now, the reason behind the error is unknown, but you can solve it by importing them separately using the following command.
import PIL
from PIL import TkImage
from PIL import Image
Example 3: Python ImportError: cannot import name _version_
Output:

from . import __version__
ImportError: cannot import name __version__
Check the __init__.py at root dir. Openpyxl read this information from the .constrants.JSON file. However, PyInstaller somehow can’t make it right. I would you write a __version__.py file by yourself and replace them in the __init__.py.
import json
import os
# Modified to make it work in PyInstaller
#try:
# here = os.path.abspath(os.path.dirname(__file__))
# src_file = os.path.join(here, ".constants.json")
# with open(src_file) as src:
# constants = json.load(src)
# __author__ = constants['__author__']
# __author_email__ = constants["__author_email__"]
# __license__ = constants["__license__"]
# __maintainer_email__ = constants["__maintainer_email__"]
# __url__ = constants["__url__"]
# __version__ = constants["__version__"]
#except IOError:
# # packaged
# pass
__author__ = 'See AUTHORS'
__author_email__ = '[email protected]'
__license__ = 'MIT/Expat'
__maintainer_email__ = '[email protected]'
__url__ = 'http://openpyxl.readthedocs.org'
__version__ = '2.4.0-a1'

Q1) How do you fix an importerror in Python?
It differs according to the mistake you have made.
All the possible solutions are discussed in the article refer it.
Q2) What is a name error in Python?
Name error is raised when the system cannot identify the variables used.
Conclusion
So, today in this article, we have seen the main reasons for ImportError: Cannot Import Name. We have seen the concept of circular dependency and how it affects our code. In the end, we have seen what things we should avoid getting into any such condition are.
I hope this article has helped you. Thank You.

@B.Goode
Sorry, I should not have pulled you up on that after all the help you have given me in the past!
My Python 2 code is shown below. I say mine, what I mean is the code I use. I have kept all my comments in the start to give credit to the person who posted it originally. I have however made extensive changes to it by adding code for the Pan/Tilt hat and adding buttons to allow easy control of the camera, including some fixed positions (all my own work!)
I have completely failed though to get it to run on my much preferred Python 3, so I stuck with this Python 2 version, which worked well until my 3B+ that I loaded with Stretch arrived a few days ago.
(My notes at the start of the Program, show that it was the cv2 command that I could not find a Python 3 equivalent for)

I am learning tkinter and trying to place an image on a Button, but I cannot get past the import.
My code:
from tkinter import *
from PIL import Image, ImageTk
The error:
No module named 'ImageTk'
Based on a post I saw when researching this I tried
sudo apt-get install python-imaging-tk
which says I already have the latest version.
I am on a Raspberry Pi3, with a new install of Raspbian and I did an upgrade and update to be sure.
Any suggestions?

Description: Python Imaging Library (Pillow fork)
The Python Imaging Library (PIL) adds an image object to your Python
interpreter. You can load images from a variety of file formats, and
apply a rich set of image operations to them.
.
Image Objects:
o Bilevel, greyscale, palette, true colour (RGB), true colour with
transparency (RGBA).
o colour separation (CMYK).
o Copy, cut, paste operations.
o Flip, transpose, resize, rotate, and arbitrary affine transforms.
o Transparency operations.
o Channel and point operations.
o Colour transforms, including matrix operations.
o Image enhancement, including convolution filters.
.
File Formats:
o Full (Open/Load/Save): BMP, EPS (with ghostscript), GIF, IM, JPEG,
MSP, PDF, PNG, PPM, TIFF, XBM.
o Read only (Open/Load): ARG, CUR, DCX, FLI, FPX, GBR, GD, ICO, IMT, IPTC,
MCIDAS, MPEG, PhotoCD, PCX, PIXAR, PSD, TGA, SGI, SUN, TGA, WMF, XPM.
o Save only: PDF, EPS (without ghostscript).

hello,
I am trying out PIL for the first time but I cannot add / download it.
Can someone help me with this?
I use pycharm for programming.
this is the code i tried:
import PIL
from PIL import Image, ImageTK

OK, it’s now installed and you should be able to import it (in your code in Pycharm or other IDE).
If you have multiple python installations, make sure that the correct one is set as interpreter in pycharm settings

Pillow is already installed for you python3.8 installation at c:pythonpython38
Now you should be able to do in Pycharm:
import PIL from PIL import Image, ImageTK
given that python3.8 (c:pythonpython38) is set as default interpreter for the project
Note that Pillow is friendly fork of PIL and replaced it long time ago.

and setup the interpreter for the project to be python3.8 with Pillow installed
Я не могу понять, как решить проблему с моим кодом, касающимся импорта ImageTK из PIL. Я искал и загружал Подушку разными способами, и ошибка кода все та же.
Traceback (most recent call last):
File "8_Age_Calculator_App.py", line 3, in <module>
from PIL import Image, ImageTK
ImportError: cannot import name 'ImageTK'
Это коды импорта файла
import PIL
from PIL import Image, ImageTK
import tkinter as tk
import datetime
И это код, который пытается импортировать изображение
main_image = Image.open('/Users/Brenden/Documents/Python_OOP/old-people-
running-illo_h.jpg')
main_image.thumbnail((100,100), Image.ANTIALIAS)
main_photo = ImageTK.Photoimage(main_image)
main_label_image = tk.Label(image=main_photo)
main_label.grid(column=1, row=0)
Как я могу решить эту проблему? Я поставлю весь сценарий в комментариях, если кто-то захочет увидеть все это. Спасибо за уделенное время.

Лучший ответ
У вас есть опечатка в модуле, который вы хотите импортировать. k в ImageTk должен быть в нижнем регистре:
from PIL import Image, ImageTk
Это должно решить вашу проблему
И в вашем скрипте есть еще одна опечатка, PhotoImage — CamelCase:
main_photo = ImageTk.PhotoImage(main_image)

#python #tkinter
Вопрос:
Когда я попытался добавить кнопку диалогового окна файла, я все время получал такую ошибку:
_tkinter.TclError: can't use "pyimage1" as iconphoto: not a photo image
Это мой код:
from tkinter import *
from PIL import ImageTk, Image
from tkinter import filedialog
from file_dialog import filedialog
root = Tk()
img = PhotoImage(file='icon.png')
root.geometry("700x500") # the application window size
root.iconphoto(False,img) #application icon
root.title("I need a NAME!") # title of window
def file_dialog():
root.filename = filedialog.askopenfilename(initialdir="Downloads", title="Select A File To Start", filetypes=(("mp4 files", "*.mp4"),("mov files", "*.mov"),("png files", "*.png"),("jpeg files", "*.jpeg"),("jpg files", "*.jpg")))
def file_dialog_button(app):
app = app.tk()
button = app.Button(app, text="Start!", command=file_dialog)
button.pack(app)
root.mainloop()
print("Succesful Build")
file_dialog()
file_dialog_button()
Комментарии:
1. Не удается воспроизвести ошибку.
2. В этом нет никакого смысла,
from file_dialog import filedialog?? Вы уже импортировалиfiledialogизtkinter3. @acw1668, когда я запустил код, он выдал
ModuleNotFoundError: No module named 'file_dialog'4. @Дерек, я удалил не относящийся к делу код и просто сосредоточился на
iconphoto()нем .5. Извините @acw1668 Я не критик, я согласен с вами
Ответ №1:
Я внес несколько изменений в ваш код, которые позволяют загружать изображения в значок корневого окна.
from tkinter import * это плохая практика, поэтому я изменил ее на import tkinter as tk и внес необходимые изменения.
Проблема заключалась в том, что вы пытались ссылаться на функции и переменные до того, как они были объявлены.
import tkinter as tk
from PIL import ImageTk, Image
from tkinter import filedialog
root = tk.Tk()
root.geometry("700x500") # the application window size
root.title("I need a NAME!") # title of window
def file_dialog():
filename = filedialog.askopenfilename(
initialdir="Downloads",
title="Select A File To Start",
filetypes=(
("mp4 files", "*.mp4"),
("mov files", "*.mov"),
("png files", "*.png"),
("jpeg files", "*.jpeg"),
("jpg files", "*.jpg")))
if filename:
root.img = tk.PhotoImage(file=filename)
root.iconphoto( False, root.img ) # application icon
app = tk.Toplevel(root)
app.transient( root )
button = tk.Button(app, text="Start!", command=file_dialog)
button.pack(fill = "both", expand = True)
root.mainloop()
print("Successful Build")
Комментарии:
1. по крайней мере , вы изменили импорт для
tkinter, но зачем импортировать изPIL, если вы его не используете? кроме того, что это за заявление о печати? он будет отображаться только тогда, когда вы закроете окно , а это значит, что он будет больше похож наsuccessful build destruction, в противном случае отличный ответ
Ответ №2:
- В соответствии с вашей ошибкой проблема в формате вашего файла, измените формат значка окна tkinter на
.ico. Значок может быть только в.icoформате. - Удалите этот
from file_dialog import filedialogимпорт, вы уже импортировали файловый журнал из tkinter. - Измените окно вашего приложения на
TopLevel()окно. Вы можете узнать о них больше здесь - В своем вызове
file_dialog_button()вы не передали значение переменнойapp.
Ваш окончательный код должен выглядеть следующим образом:
from tkinter import *
from PIL import ImageTk, Image
from tkinter import filedialog
root = Tk()
img = PhotoImage(file='icon.ico')
root.geometry("700x500") # the application window size
root.iconphoto(False,img) #application icon
root.title("I need a NAME!") # title of window
def file_dialog():
filename = filedialog.askopenfilename(initialdir="Downloads", title="Select A File To Start", filetypes=(("mp4 files", "*.mp4"),("mov files", "*.mov"),("png files", "*.png"),("jpeg files", "*.jpeg"),("jpg files", "*.jpg")))
def file_dialog_button(app):
app = Toplevel()
button = Button(app, text="Start!", command=file_dialog)
button.pack(app)
print("Succesful Build")
file_dialog()
file_dialog_button('exmaple_name')
root.mainloop()
Комментарии:
1. одно небольшое дополнение: я настоятельно не рекомендуем использовать подстановочный знак (
*) при импорте что-то, вы должны либо импортировать то, что вам нужно, например,from module import Class1, func_1, var_2и так далее, либо импортировать весь модуль:import moduleвы также можете использовать псевдоним:import module as mdили sth, как это, дело в том, что не все импортное, если вы на самом деле знаете, что Вы делаете; наименование столкновения эту проблему.2. что в основном означает, что их первая строка должна выглядеть так
from tkinter import Tk, Toplevel, Button. также вы либо используетеPIL, что означает этоImageTk.PhotoImage, иImage.open()или удаляете этот импорт и добавляетеPhotoImageв первую строку импорта:from tkinter import Tk, Toplevel, Button, PhotoImage

Коллеги,
пытаюсь запустить /usr/sbin/image-to-gcode получаю при попытке скормить в обработку файл png сообщение об ошибке —
Понятное дело, стоит python2-pillow, python-pilkit, LinuxCNC. Но где найти и как поставить ImageTk module? В итоге выяснилось, что во всем виноват зоопарк питонов и мелочи. б) — этот вариант нужен для вызова утилиты из самого LinuxCNC КАК ВСЕГДА ОГРОМНОЕ СПАСИБО ЗА ОТЗЫВЧИВОСТЬ, ОПЕРАТИВНОСТЬ VS220 & VASEK!!! |

pacman -Qo /usr/sbin/image-to-gcode /usr/bin/image-to-gcode принадлежит linuxcnc-sim 2.7.14-2 Блин. А оно ведь у меня есть — pacman -Qo /usr/lib/python3.7/site-packages/PIL/ImageTk.py Но при этом результат выше. Как их подружить?
то сообщение об ошибке меняется (на стадии выбора файла png), но не существенно —
Если же поставить программу отсюда — https://www.cnc-club.ru/forum/viewtopic.php?t=3541, то сообщение об ошибке лаконичнее —

Приветствую уважаемое сообщество.
Прошу помочь новичку преодолеть )
Не могу понять, как исправить ошибку, упорно возникающую при попытке открыть изображение не во внеших программах, а непосредственно в python.
Если вызываю изображение в браузер таким способом — окрывает:
import webbrowser
webbrowser.open(«D:PtRs.jpg»)
Если открываю то же изображение в gif через tkinter — работает:
from tkinter import *
root = Tk()
im = PhotoImage(file=’D:PtRs.gif’)
l = Label(root, image=im)
l.pack()
root.mainloop()

Таким способом тоже открывается в системном вьювере:
from PIL import Image
image = Image.open(‘D:\Pt\flowers-over-white-background.jpg’)
image.show()
А когда пытаюсь открыть jpg, png с использованием PIL в окне python — выдает ошибку:
Пример:
from PIL import Image
sample = Image.open(‘D:PtRs.jpg’)

Или вот , тоже ошибка:
import tkinter
from PIL import Image, ImageTk
root = tkinter.Tk()
# создаем рабочую область
frame = tkinter.Frame(root)
frame.grid()
#Добавим метку
label = tkinter.Label(frame, text=»Hello, World!»).grid(row=1,column=1)
# вставляем кнопку
but = tkinter.Button(frame, text=»Кнопка»).grid(row=1, column=2)
#Добавим изображение
canvas = tkinter.Canvas(root, height=400, width=700)
image = Image.open(«D:PtRs.jpg»)
photo = ImageTk.PhotoImage(image)
image = canvas.create_image(0, 0, anchor=’nw’,image=photo)
canvas.grid(row=2,column=1)
root.mainloop()
