Hi,

 

I have a Python script that trains a TensorFlow model. Python is installed in a Conda environment.

 

When the Python script is run from a command prompt, the model is trained on GPU. But when the script is run from Delphi PythonEngine, the model is trained on CPU instead.

 

Would anyone has an idea why I am not able to use GPU with Python4Delphi?

 

Thanks.

the first thing that comes to mind is that some configuration settings are "lost" due to the fact that the current directory may be different

(or some logic related to this is broken)

 

also check this: https://www.tensorflow.org/guide/gpu

you can do some diagnostic this way

Process monitor from Sysinternals is your friend here. Trace the startup and see where the file is not found.

 

Python at the command prompt is built with vcruntime, and Delphi does not. Put a copy of msvcp140.dll and vcruntime140_1.dll in the directory that has your EXE and then see if works correctly.

Thank you for your advice.

 

Despite using the same working directory, TensorFlow is indeed loading CUDA DLLs from a different location with Python4Delphi.
