CUDA error: CUBLAS_STATUS_INTERNAL_ERROR when calling `cublasCreate(handle)`

I see this has been posted a few times before, but none of those responses have helped.

From here, I’m trying:

CUDA_LAUNCH_BLOCKING=1 && export CUDA_VISIBLE_DEVICES=0 && python train_transformer_encoder.py --batch_size 1

But I’m getting:

Traceback (most recent call last):
  File "train_transformer_encoder.py", line 207, in <module>
    main()

    return torch._C._nn.linear(input, weight, bias)
RuntimeError: CUDA error: CUBLAS_STATUS_INTERNAL_ERROR when calling `cublasCreate(handle)`

So I’ve tried a batch_size of 1 and the CUDA_LAUNCH_BLOCKING as well, but no dice. Any help would be greatly appreciated.

Thank you in advance

Also - I want to add that when. I run on CPU, it’s fine.

I created a MUCH simpler example:

import torch

if __name__ == "__main__":
    DEVICE = torch.device("cuda" if torch.cuda.is_available() else "cpu")

    m = torch.nn.Linear(20, 30).to(DEVICE)
    input = torch.randn(128, 20).to(DEVICE)
    output = m(input)
    print('output', output.size())
    exit()

and get the same error.

I am joining the wagon.

I am getting the same error as @shamoons on the same example. The fix of CUDA_LAUNCH_BLOCKING=1 and CUDA_VISIBLE_DEVICES=0 did nothing. Running on CPU works well.

This operation succeeds:

>>> a = torch.tensor([1]).cuda()
>>> b = torch.rand([1]).cuda()
>>> c = a + b
>>> print(c)
$ tensor([2], device='cuda:0')

The following throws the original error in this post

>>> l = torch.nn.Linear(1, 1).cuda()
>>> a = torch.tensor([1.]).cuda()
>>> l(a)

My specs:
PyTorch version: 1.8.0
CUDA version: 11.0

PARTIAL FIX:

It seems that downgrading to PyTorch version 1.7.1 fixed the issue for me. This is obviously not idea, but maybe it can help you too @shamoons.

It would still be nice to hear from official sources to see if they have something to say :smiley: (thank you a lot torch devs and admins for making our lives better)

It helped with the simple case by downgrading. But now my actual code has the same error. If it matters, I’m using a virtual environment.

Can you share the same specs that I shared for my system above? Hopefully we can figure something out

Are you on Discord or something perhaps? We can screen share

@shamoons @Daniel_Hernandez could you both post the output of python -m torch.utils.collect_env?

@Daniel_Hernandez 's env shows CUDA11.0, which is not shipped in the 1.8.0 binaries (10.2 and 11.1 are used), so I’m unsure where this package comes from. Did you build it from source?

If you are using the 10.2 pip wheels (not conda), note that sm_75 was pruned from them and you would have to use the 11.1 pip wheels.
This issue is also tracked here.

It’s the legendary @ptrblck! Thank you a lot, truly.

I am going to post 2 different calls to python -m torch.utils.collect_env. One from my system environment using version 1.7.1 and another using torch 1.8.0 on a virtual environment. Oddly enough it seems that torch is using a different CUDA version than what’s specified in nvidia-smi! (it’s using 10.2, instead of 11.0).

Torch version 1.7.1 where the original error message DOES NOT appear:

Did you build from source?

No, I installed via pip install torch with pip version 20.0.2 on Python version 3.8.5. The pip version inside my virtualenv is 21.0.1

I am sorry for the noob question. How might I install the 11.1 pip wheels? (assuming that 11.1 refers to the conda version)

Thanks again!

That’s expected, since the pip wheels and conda binaries ship with their own CUDA runtime.
Your local CUDA toolkit (shown via e.g. nvidia-smi) would be used if you are building a custom CUDA extension or PyTorch from source.

Thanks for the env information. Based on this, you are indeed using the pip wheels with the CUDA10.2 runtime, which are broken on the Turing architecture (see the linked issue).

11.1 refers to the CUDA runtime version. You can install it by selecting CUDA 11.1 here:

pip install torch==1.8.0+cu111 torchvision==0.9.0+cu111 torchaudio==0.8.0 -f https://download.pytorch.org/whl/torch_stable.html

Oh yeah! It worked! And I’ve now learnt that pip wheels ship with their own CUDA runtime!

Installing torch with CUDA 11.1 with the following command did fix the initial issue with torch 1.8:

 pip install torch==1.8.0+cu111 torchvision==0.9.0+cu111 torchaudio==0.8.0 -f https://download.pytorch.org/whl/torch_stable.html

May you have an amazing day! Good luck @shamoons with you issue, do try out @ptrblck’s suggestions and hopefully you’ll be set!

I installed torch via conda install pytorch cudatoolkit=11.3

Could you post a minimal, executable code snippet to reproduce this issue, please?

Hey there,
I have encountered the same problem as @skpig .
I ran the simple code given by shamoons (as shown below) in two different GPUs, which are Tesla V100-PCIE-32GB, and NVIDIA A100-SXM-80GB

import torch

if __name__ == "__main__":
    DEVICE = torch.device("cuda" if torch.cuda.is_available() else "cpu")

    m = torch.nn.Linear(20, 30).to(DEVICE)
    input = torch.randn(128, 20).to(DEVICE)
    output = m(input)
    print('output', output.size())
    exit()

The code above run fine on Tesla V100, but when it runs on NVIDIA A100, it throws out the following error:

RuntimeError: CUDA error: CUBLAS_STATUS_NOT_INITIALIZED when calling `cublasCreate(handle)`

I then execute python -m torch.utils.collect_env for both GPUs to try find any discrepancies between the two GPUs I’m testing on.
For Tesla V100, it gave:

I’m wondering what causes this issue and how to solve it. Any help is really appreciated :slight_smile:

It seems the CUBLAS_STATUS_INTERNAL_ERROR changed to CUBLAS_STATUS_NOT_INITIALIZED which could point towards a setup issue.
Was this setup working in the past and if so, did you update the drivers without a reboot etc.?

I’m not really sure as this is my first time using the Nvidia A100 GPU.
If this is a setup issue, I’ll ask my administrator then about this issue. Thanks for the reply
