I find that everything just works fine if Python path doesn't contains any Chinese characters. But if the path contain some Chinese chars, let's said, start a python interactive shell via the following command:
D:\中文测试\CCInsight\python-3.8.10-embed-amd64\python.exeAnd then when I run import clr, the following error will be raised.
>>> import clr
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "D:\中文测试\CCInsight\python-3.8.10-embed-amd64\lib\site-packages\clr.py", line 6, in <module>
load()
File "D:\中文测试\CCInsight\python-3.8.10-embed-amd64\lib\site-packages\pythonnet\__init__.py", line 143, in load
if func(b"") != 0:
File "D:\中文测试\CCInsight\python-3.8.10-embed-amd64\lib\site-packages\clr_loader\types.py", line 64, in __call__
return self._callable(ffi.cast("void*", buf_arr), len(buf_arr))
RuntimeError: cannot call null pointer pointer from cdata 'int(*)(void *, int)'
I delivery a software that provide a GUI depends on pythonnet, this become an annoy bug as user may choose their own installation location, which may contain Chinese chars. Hope to find a fix or a work around.
Update:
I try to narrow down the scope of code to
https://github.com/pythonnet/clr-loader/blob/master/clr_loader/netfx.py#L36-L44
It looks to me like the _get_callable failed to get the right callabe object by the following args
assembly_path: d:\中文测试\CCInsight\python-3.8.10-embed-amd64\lib\site-packages\pythonnet\runtime\Python.Runtime.dll
typename: Python.Runtime.Loader
funcname: Initialize
