External Email - Use Caution Thank you for the suggestions. It appears now to be seeing the DNN libraries. However, now I get:
OOM when allocating tensor with shape[1,256,256,160,24] and type float on /job:localhost/replica:0/task:0/device:GPU:0 by allocator GPU_0_bfc My GPU has 4Gb RAM and the CPU has 32 Gb RAM. Is this error occurring because of insufficient GPU RAM? What are the requirements of the GPU for mri_synthseg? Is there a workaround for this? For those who may be having the same trouble configuring the GPU for FreeSurfer 7.4.0 in WSL, I installed an old Nvidia Game Ready Driver 522 <https://www.nvidia.com/download/driverResults.aspx/193713/en-us/> (for my GPU) in Windows, which installed CUDA 11.8 support. In WSL, I installed CUDA 11.8 toolkit <https://developer.nvidia.com/cuda-11-8-0-download-archive> WSL-Ubuntu version using instructions from Nvidia website and CuDNN 8.6.0 <https://developer.download.nvidia.com/compute/cuda/repos/ubuntu1804/x86_64/libcudnn8_8.6.0.163-1+cuda11.8_amd64.deb>. I then had to ensure the CuDNN libraries were in the LD_LIBRARY_PATH using: export LD_LIBRARY_PATH="/usr/lib/wsl/lib:/lib/x86_64-linux-gnu" This seemed to work, except I received the above mentioned out of memory error.
