Question

我在Windows 7 64位系统上使用WinPython 64位，使用Python 3.4和matplotlib 1.5.1。我无法以tiff格式保存我的情节，例如：

import matplotlib.pyplot as plt

fig, axs = plt.subplots()
fig.savefig('mpl_tiff.tif', dpi=300)

它会说：

runfile('C:/Users/Administrator/Downloads/mpl_tiff.py', wdir='C:/Users/Administrator/Downloads')

Traceback (most recent call last):

  File "<ipython-input-8-6a562331465e>", line 1, in <module>

有人可以提供解决方案吗？谢谢！

PS：我从谷歌上搜索这可能是问题所在：https://github.com/python-pillow/Pillow/issues/1524

但解决方案仍不明确。

Python中的Matplotlib无法保存tiff
