导入 matplotlib.backends.backend_tkagg - ModuleNotFoundError：没有名为“PIL”的模块

Question

I am using python 3.8.5 and running on Windows 10. I tried to insert a plot in Tkinter Gui, but when I import matplotlib.backends.backend_tkagg , it raises the error shown below. Mathplotlib and Tkinter versions are the latest versions 8.6 and 3.3.1, respectively. And I also installed the "Pillow" module.

>>>import matplotlib.backends.backend_tkagg

Here also is the error -

Answer 1

If you are using anaconda try

conda install pillow

if you are using pip try:

pip install Pillow

Make sure you are installing to the right environment. The import should then work.
