spleeter: [Bug] spleeter-gpu is unusable out of the box

Description

I tried, once again, to get spleeter running on the GPU, but I just can’t do it. I never directly worked with TensorFlow or any other ML software package, so I can’t even begin to debug this.

Step to reproduce

1. Install CUDA 10.2 on a fresh, fully up-to-date Windows 10 installation
2. Install Miniconda
3. Install spleeter-gpu using conda install -c conda-forge spleeter-gpu in the Anaconda Prompt
4. Run spleeter separate -o Spleeter -m -p spleeter:2stems-16kHz -i "audiofile.m4a"

Output
