Когда я пытался сохранить фигуру matplotlib в файл, я получал ошибку описания плохого файла. Мой код выглядит следующим образом:
import os
os.chdir('C:\\users\\mutas\\documents\\')
import matplotlib.pyplot as plt
plt.text(0.5,0.5, 'some text')
if os.path.isfile('c.png'):
plt.savefig('c.png')
При запуске возникает следующая ошибка:
OSError: [Errno 9] Bad file descriptor
The above exception was the direct cause of the following exception:

Что здесь происходит? Обратите внимание, что это не новая установка matplotlib в системе. Я уже некоторое время использую это, и эта проблема внезапно начала возникать.
