GPU not recognized after Cryosparc v4.5.1 update

Install, Configure and Update
1

Hi After Cryosparc 4.5.1 update, my GPUs (4x GeForce TRX 2080Ti) are no longer recognized in Cryosparc.

I typed three commands typically used for troubleshooting. Here are the outcomes.

I greatly appreciate your help!

Pei

cryosparcm cli “get_gpu_info()”

None

./bin/cryosparcw gpulist

Detected 4 CUDA devices.

@peizhou These outputs look normal. Please keep in mind that it is not the purpose of the get_gpu_info() function to print GPU information to the screen. Are you experiencing any issues processing data after the CryoSPARC update?

I used to have problems for GPUs not being recognized. I traced it down to a wrong CUDA symbolic link while waiting for response. I thought get_gpu_info() tells me whether CUDA is recognized. It was a false alarm. When I test the run, it is running fine (just as you suggested). Many thanks for your explanation.
