error while running guppy 4.4.1 on GPU mode

[sanaek]

Hi, im currently trying to run guppy on a cluster with GPU mode and I get the following error

[guppy/error] main: CuBLAS error at /builds/ofan/ont_core_cpp/ont_core/basecall_core/nn_caller_cuda.cpp:1138: 1 [guppy/warning] main: An error has occurred. Aborting

I'm using the following code

guppy_basecaller --input_path /fast5_9a --save_path fastq -r -x "auto" --compress_fastq -c dna_r9.4.1_450bps_fast.cfg

Can anyone help me on this?

Than you

same error here, from command line

I was running CUDA version 10.2 When updating via the ONT debian repo, this warning pops up: The following packages have unmet dependencies: ont-guppy : Depends: libcuda-11.1-1 or libcuda1 (>= 455)
Looks like I need to update CUDA :'(

[iiSeymour]

Yes but you can install CUDA 11.1 alongside CUDA 10.2.

Hi, I have the same problem GPU mode with those versions: guppy 4.4.1 (working well alone) megalodon I have 2.2.9 ont_pyguppy_client_lib 0.0.9

the HPC admins here won't have libCUDA11 installed before March, is it really what is needed to solve the problem? @noncodo did it work for you?

thanks in advance

Not feeling brave enough to install a local version of CUDA on the HPC... will also wait for the admin to do the upgrade...

Hi, has anyone succeeded with installation of CUDA v11.1 without updating the drivers? Our sysadmins updated CUDA (new version is loaded via module load),

$ nvcc --version
Build cuda_11.1.TC455_06.29190527_0

but guppy 4.4+ still fails with an error.

[guppy/error] main: CuBLAS error at /builds/ofan/ont_core_cpp/ont_core/basecall_core/nn_caller_cuda.cpp:1138: 1
[guppy/warning] main: An error occurred initialising the basecaller. Aborting.

nvidia-smi still shows old CUDA version...

$ nvidia-smi
| NVIDIA-SMI 440.82       Driver Version: 440.82       CUDA Version: 10.2     |

Does the new CUDA has to be bound to the drivers somehow? Or is it related to module load somehow?

We were seeing the same issue with guppy Version 4.5.2+bcc53d3. Updated the nvidia driver to NVIDIA-SMI 460.67 Driver Version: 460.67 CUDA Version: 11.2 and all seems well. You'll still need cuda_11 through your module load.

The nvidia-smi - shows what the driver installed is capable of running for CUDA versions. The actual CUDA version is in the compiler and the nvidia-cuda-toolkit, etc.

If you wish to use the new driver with CUDA 11.* support: apt install nvidia-driver-460 For Cuda versions: for example in case your packages vary apt search cuda-toolkit apt install nvidia-cuda-toolkit cuda-toolkit-11-2

$ nvidia-smi | head -3 Mon Apr 12 15:54:29 2021
+-----------------------------------------------------------------------------+ | NVIDIA-SMI 460.56 Driver Version: 460.56 CUDA Version: 11.2 |

You can run CUDA 10 on a NVIDIA 460.56 driver (that has support for CUDA 11.2). If that makes it clearer.

Has this worked for anyone? @markwdalton I tried updating the drivers to 460.67 and CUDA 11.2, and still getting the same error. If you are using Docker, can you please share your Dockerfile? I have no trouble running Guppy outside of docker but inside the docker, it throws this error:

CuBLAS error at /builds/ofan/ont_core_cpp/ont_core/basecall_core/nn_caller_cuda.cpp:163: 13
