python - 尝试用石榴绘制 HMM 时出现 Errno 13

Question

我正在尝试绘制一个 HMM 模型，通过使用 Pomegranate 库来实现。

调用 plot 方法model.plot()调用以下错误：

PermissionError                           Traceback (most recent call last)
<ipython-input-29-405034733d4b> in <module>
      3 #unique_data = [list(x) for x in set(tuple(x) for x in result)]
      4 #unique_data
----> 5 model.plot()

   1519             fh.write(data)
   1520             if is_string_like(path):

   1545                 fh = os.popen("bzcat " + path)  # probably not portable
   1546             else:
-> 1547                 fh = open(path, mode=mode)
   1548         elif hasattr(path, 'write'):
   1549             # Note, mode of file handle is unchanged.

PermissionError: [Errno 13] Permission denied: 'C:\\Users\\renda\\AppData\\Local\\Temp\\tmp672ou8lg'

我试图更改文件夹的 R/W 权限，但没有成功。有什么建议吗？我正在使用 Anaconda3 环境在 Windows 10 上工作。
