networkx package is not visible in singularity container image

[Larz60+]

please execute commands:

• Python -V
  
• pip -V
  
• Show results in a new post.
  
• Make sure singularity Container environment is activated if you find wrong pip is being used.
  

also, privately run pip list from command line and make sure you see your container, etc.
I think the pip that you have in singularity container is not the one being run.
Above simple test will show if this is true.
