GPU version finally works for me. Here are the steps...

I spent the entire weekend trying to get spleeeter to work with GPU (maybe I'm slow...). I could make combinations of versions work with the CPU, but the command line always failed with the GPU enabled. The following steps finally worked!

I don't show the steps to clone the spleeter project from github, since these files were already in place from previous attempts. Also note: I only tested the command line version of 'separate.' Since this worked, I'm going to assume (for now) that the problem is solved. At least it is running with the GPU. If I had more time, I suppose I could increase the version of cudnn and the tools until it failed. I'd be interested if someone else got it working with a more recent rev.

I have an Asus G14 Zephyrus with an NVIDIA GeForce RTX 3060 Laptop GPU and an AMD Ryzen 9 5900HS.

Here are the steps:

1. From Anaconda Navigator, I created a new environment with Python 3.9.7 and a CMD.exe Prompt.

2. From the new CMD Prompt, I typed the following commands:

(Python_3_9_7) C:\Users\windo>conda create -n tensorflow2.5 python=3.9
(Python_3_9_7) C:\Users\windo>conda activate tensorflow2.5
(tensorflow2.5) C:\Users\windo>conda install cudatoolkit=10.0.130
(tensorflow2.5) C:\Users\windo>conda install cudnn=7.3.1
(tensorflow2.5) C:\Users\windo>pip3 install tensorflow-gpu==2.5
(tensorflow2.5) C:\Users\windo>conda install -c conda-forge ffmpeg libsndfile
(tensorflow2.5) C:\Users\windo>pip install spleeter

(tensorflow2.5) C:\Users\windo>nvcc -V
