Describe the bug A clear and concise description of what the bug is. I want to follow the tutorial to generate the Criteo dataset, when I build the docker image using the Dockerfile_preprocessing file, I got the error.

To Reproduce Steps to reproduce the behavior:

1. git clone https://github.com/NVIDIA/DeepLearningExamples.git
2. cd DeepLearningExamples/PyTorch/Recommendation/DLRM
3. docker build -t nvidia_dlrm_preprocessing -f Dockerfile_preprocessing . --build-arg DGX_VERSION=DGX-A100

Expected behavior A clear and concise description of what you expected to happen.

# docker build -t nvidia_dlrm_preprocessing -f Dockerfile_preprocessing . --build-arg DGX_VERSION=DGX-A100
