amazon-sagemaker-bert-pytorch failed to run

[yzhang-github-pub]

I cloned https://github.com/aws-samples/amazon-sagemaker-bert-pytorch.git in SageMaker, and ran jupyter notebook without any modification, and got error as below:

"UnexpectedStatusException: Error for Training job pytorch-training-2020-10-27-16-28-37-955: Failed. Reason: AlgorithmError: ExecuteUserScriptError:

Hi,

I’ve also had same kind of problem since the last Monday (just this week).
I can’t run pytorch code on SageMaker instance(ml.p3.8xlarge and local mode).
However I could run and complete learning jusing same code last Friday.

I got AlgorithmError: ExecuteUserScriptError, but my algorithm log (I use CloudWatch) is :
����������| 207659/210805 [03:27<00:02, 1050.67it/s]#15 99%|����������| 210753/210805 [03:30<00:00, 1048.70it/s]#015100%|����������| 210805/210805 [03:30<00:00, 999.88it/s]
-- | --
tqdm outputted garbled characters.

I would like to know any workaround.
Thank you very much for your help.

Hi,

I have the same issue as above. Code that worked perfectly 2 weeks ago and where I changed nothing, now that same code does not run.

There is something seriously wrong with the pytorch estimator of sagemaker. This should be looked at.

Thank you

Ran into the same issue but was able to get the training job to run using pytorch framework_version == 1.6.0 and updating the version of transformers==3.5.0. But when trying to deploy an endpoint:

predictor = estimator.deploy(initial_instance_count=1, instance_type="ml.m4.xlarge")

I get this error:

and

FileNotFoundError: [Errno 2] No such file or directory: '/opt/ml/model/model.pth'

Did something change in the PyTorch image?

[lawwu]

Updating the requirements.txt to

tqdm
requests==2.22.0
regex
sacremoses
sentencepiece==0.1.91
transformers==3.5.0

and using the pytorch 1.5.0 image worked for me.

[NeuroWinter]

I am getting the exact same issue, using pytorch 1.5.0 does not work for me with the above requirements, nor does the following requirements with 1.6.0:

pycm 
tqdm 
requests==2.22.0 
regex 
sacremoses 
sentencepiece==0.1.91 
# transformers==3.5.0 Does not work with pytorch v 1.5- 1.6 
transformers==4.0.0 `

The sagemaker version in the notebook is as follows:

sagemaker==2.18.0 
sagemaker-pyspark==1.4.1 

[icywang86rui]

This change to switch to TorchServe broke some workflows when the training job doesn't save the model to "/opt/ml/model/model.pth". See aws/sagemaker-pytorch-inference-toolkit@a3a08d0
This change is released in the 1.6 PT container. The solution of providing a custom save_pytorch_model method mentioned here should work - https://github.com/aws/sagemaker-pytorch-inference-toolkit/issues/86​. Another workaround is to switch to 1.5 or older versions of PyTorch images.

Hi, still facing the same error

[georgebakas]

The issue is not yet addressed. I am trying to deploy a custom Detr model with PyTorch (based on HuggingFace implementation and trained with Pytorch for custom object detection). I am using PT v1.11 and Python 3.8. The weights are structured in the same way that is stated in the aws/pytorch documentation:
https://sagemaker.readthedocs.io/en/stable/frameworks/pytorch/using_pytorch.html#for-versions-1-2-and-higher

The deployment is performed on a ml.m4.xlarge and the error I get is that the weights are not found.

W-9000-model_1.0-stdout MODEL_LOG - FileNotFoundError: [Errno 2] No such file or directory: '/opt/ml/model/model.pt'

Could you please clarify where are the model weights expected to be? Or please provide container Dockerfile in order to check.

[akrishna1995]

Thanks for raising this issue. Can anyone confirm if this issue still persists on the latest sagemaker ?

[taziamoma]

I'm having this exactly issue despite including transformers in my requirements.txt file. Mine is being handled by sagemaker though, I'm not uploading a model.
