Because numpy library and the library version will matplotlib conflict, if a version mismatch error will be a variety of fancy! ! ! (Windows10)
I experienced a few hours to try various methods under, and finally resolved all error, can be used normally matplotlib library pycharm in.
Record what solutions :::
(1) mumpy version matplotlib libraries and libraries I installed as follows:
matplotlib: 3.1.3
numpy: 1.18.1
python: 3.8
1. Check the installed version of the library pycharm method:
Or:
Open file-> Settings
2. Terminal View:
(2) proper installation:
1. Install numpy library
Directly in the terminal
pip install numpy
Or directly in the pycharm
2. Install matplotlib
If you have installed the latest version matplotlib library, direct unloading, needless to say. Error because the version is not compatible, do not want to uninstall how to do Oh! ! !
After trying a lot of ways, I found this in the only possible way:
install matplotlib download .whl library file.
.whl file python for all kinds of third-party libraries Download
.Whl find their own version of the file to download (it must be version 3.1.3):
The last cd into the download folder;
then pip install path to the file! ! !
(Note: If the absolute path to the file)
