Unable to import psdr_cuda

[JakeXin7]

Hello and thanks for sharing your work!

I cannot find any package or module named psdr_cuda after compiling the system. I can only find one pyd file in psdr-cuda\build\lib\Release(or psdr-cuda\build\lib) named psdr_cuda.cp39-win_amd64.pyd. I wonder if this is the right result after compiling? Did I make any mistake while compiling the system?

This seems to be correct. Have you add psdr-cuda\build\lib\Release to your python path? Also, make sure enoki build is also in your python path

[JakeXin7]

Yeah, I did. And I also tried:

import sys import os sys.path.append('D:/study/CG/psdr-cuda/build/lib') os.environ['path'] += ';D:/study/CG/psdr-cuda/build/lib' import psdr_cuda

to import psdr_cuda, but it didn't work.

[JakeXin7]

The error is:

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

I just make an update, can you pull and rerun?

[JakeXin7]

I pull and rerun the system, but errors still occur. I got some warning while compiling. Did these warnings matter?

[andyyankai]

warnings are fine. Are you able to import enoki?

[andyyankai]

gonna sleep, remember to double-check if enoki is in your PATH and PYTHON PATH. Here is a guide: https://docs.oracle.com/en/database/oracle/machine-learning/oml4r/1.5.1/oread/creating-and-modifying-environment-variables-on-windows.html

[JakeXin7]

I fix the problem by change the interpreter from python of Windows to a virtual environment created by Anaconda! (But I don't know why it helps) Thanks for help!

[andyyankai]

one possible reason is that you are using python3.9, while the default enoki precompiled pkg is python3.8

This seems to be correct. Have you add psdr-cuda\build\lib\Release to your python path? Also, make sure enoki build is also in your python path

In windows10，After successful compilation,I add the Python path(psdr-cuda,enoki),but it doesn't work.Did I add it the wrong way?

# In run_test.py
import sys
sys.path.append(r'D:\C++Program\psdr-cuda\ext_win64\enoki\lib') 
sys.path.append(r'D:\C++Program\psdr-cuda\build\lib\Release')
