Error deploying GraphRAG Backend container

[richross]

Describe the bug
I am deploying the GraphRAG Accelerator solution in my Azure tenant.

I downloaded the repo from GitHub.
I reopened the repo in VS Code in a devcontainer.
I followed the Deployment Guide Quickstart to set the variables (required variables only).
I opened a bash terminal in VS Code and used the command
bash ./deploy.sh -p deploy.parameters.json
to launch the deployment.

All of the Azure components deployed successfully.

The deploy.sh script is failing at the deployDockerImageToACR step. I get the following relevant output:

Run failed

It is failing on the python command from the Dockerfile-backend line 21.
The error states there is no module nltk.
According to the output from the container build, It did install nltk version 3.9.1.

Please let me know if there is any additional information I can provide to troubleshoot this. I looked through the existing issues and did not see anything related to this error.

Thanks for your help!
