ImportError: DLL load failed while importing _stir: The specified module could not be found.

this occurs after installation by Conda, and import stir

I see a similar issue marked closed, but still dont know how to solve it.

Please check conda-forge/stir-feedstock#106. It contains some ways to diagnose and ways to solve the problem. Apologies for this. Let us know.

@KrisThielemans thanks for the help, looks like it is related to _stir.pyd file can not be found correctly, I tried to add the path of _stir.pyd into code, but still not work, I'm wondering if it has sth to do with python version that used to pack the pyd file? what python version is it?

[KrisThielemans]

That's unlikely to be it. Conda/conda-forge automatically match python versions, set the path etc. (conda-forge builds a few version of STIR for a few different python versions, but you shouldn't have to worry about that).

Debugging this via python is hard, because its message is not very helpful. Did you try running a STIR executable as in the stir-feedstock issue above?

Hi. I'll close this issue if there are no further updates.
