Hi,

I met this problem during refine step even if I downloaded the right tensorflow-gpu version. **10-20 11:26:01, INFO

Isonet starts refining

10-20 11:26:05, ERROR No GPU detected, Please check your CUDA version and installation 10-20 11:26:05, ERROR Traceback (most recent call last): File "/home/spuser/IsoNet/bin/refine.py", line 25, in run run_whole(args) File "/home/spuser/IsoNet/bin/refine.py", line 105, in run_whole check_gpu(args) File "/home/spuser/IsoNet/bin/refine.py", line 275, in check_gpu raise RuntimeError('No GPU detected, Please check your CUDA version and installation') RuntimeError: No GPU detected, Please check your CUDA version and installation**

Here is my system info: System: Centos 7, CUDA version: 10.2 Driver version: 440.31 GPU: 4X RTX2080Ti

Any thoughts?

Best, Pengxin

Hi Pengxin,

What is the version of cudnn?

[Pengxin1028]

My cudnn version is cudnn8-8.2.4

Did you check whether your versions matches the ones in table? I can not guarantee that cuda10.2 will work because it is not listed. https://www.tensorflow.org/install/source#gpu

Much appreciate your help!

I got the same error but in my case it was because I had the wrong version of tensorflow-gpu. Pip would not install version 2.3 because of dependency requirements not met. Finally I got it to install it by downgrading python from 3.9 to 3.8. This solved the issue and now isonet training is running smoothly.

Dear team,

I got the similar error since I updated CUDA to 12.2. as below:

2024-04-08 13:46:35.112110: E external/local_xla/xla/stream_executor/cuda/cuda_driver.cc:274] failed call to cuInit: CUDA_ERROR_NO_DEVICE: no CUDA-capable device is detected

File "/data/IsoNet/bin/refine.py", line 227, in check_gpu raise RuntimeError('No GPU detected, Please check your CUDA version and installation') RuntimeError: No GPU detected, Please check your CUDA version and installation

I already installed tensorflow 2.15.0 and python3.9 for the isonet conda environment to match cuda 12.2. Could you help me in this please?
