matplotlib を使用して、LaTeX 用の pgf ファイルを作成しようとしています。
from matplotlib.pyplot import subplots
from numpy import linspace
x = linspace(0, 100, 30)
fig, ax = subplots(figsize = (10, 6))
ax.scatter(x, x)
fig.tight_layout()
fig.savefig('/home/mark/dicp/python/figure.pgf')
しかし、私は得るOSError: [Errno 2] No such file or directory
:

また、出力ファイルの次の部分も生成します。

...保存しようとしているファイルは書き込み可能です。私は何かを誤解していますか、それともこれは報告すべきバグですか?
