pyinstaller生成oct2py导入的可执行文件错误

Question

我试图使一个python可执行文件使用oct2py来评估一个. m文件。python脚本独立运行良好。我已经成功地使用pyInster制作了一个可执行文件（使用--onefile，在构建它时没有错误），但是当我运行这个可执行文件时，我得到了以下错误，可执行文件退出了：

C:\Users\Jason\Desktop\Oct2Py test>readFolder.exe
error: '_pyeval' undefined near line 1 column 1
Traceback (most recent call last):
  File "site-packages\scipy\io\matlab\mio.py", line 33, in _open_file
FileNotFoundError: [Errno 2] No such file or directory: 'C:/Users/Jason/AppData/Local/Temp/tmpbn8aefsj/reader.mat'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "readFolder.py", line 8, in <module>
    octave.eval('pkg load io')
  File "site-packages\oct2py\core.py", line 484, in eval
  File "site-packages\oct2py\core.py", line 369, in feval
  File "site-packages\oct2py\core.py", line 565, in _feval
  File "site-packages\oct2py\io.py", line 28, in read_file
  File "site-packages\scipy\io\matlab\mio.py", line 141, in loadmat
  File "site-packages\scipy\io\matlab\mio.py", line 64, in mat_reader_factory
  File "site-packages\scipy\io\matlab\mio.py", line 39, in _open_file
FileNotFoundError: [Errno 2] No such file or directory: 'C:/Users/Jason/AppData/Local/Temp/tmpbn8aefsj/reader.mat'
[1456] Failed to execute script readFolder

看来这个问题是第一次出现在“百万富翁”身上。py’，但我不知道它在哪里寻找‘阅读器’。垫子'。我认为“读者”。mat'是由oct2py创建的某种临时文件。

只是为了确保python脚本正确运行并计算引用的整个oct2py。m文件正确。

谢啦

python 3.7，pyInster 3.5开发，oct2py 4.0.6。

有同样的问题，从这里得到了答案：https://github.com/blink1073/oct2py/issues/144

解决方案似乎是将一个临时文件夹作为参数传递给oct2py。

import oct2py
os.makedirs(temp_folder, exist_ok=True)
octave = oct2py.Oct2Py(temp_dir=temp_folder)
