When i run `make test-submission` locally, I get this error

> - echo ‘Running code submission with Python’  
> Running code submission with Python
> - conda run --no-capture-output -n condaenv python main.py  
> Traceback (most recent call last):  
> File “/code\_execution/main.py”, line 7, in

> ImportError: libGL.so.1: cannot open shared object file: No such file or directory  
> ERROR conda.cli.main\_run:execute(47): `conda run python main.py` failed. (See above for error)

I am using the image: [visiomelmelanoma.azurecr.io/visiomelmelanoma-competition:gpu-latest](http://visiomelmelanoma.azurecr.io/visiomelmelanoma-competition:gpu-latest) (220af7795b9c)

Has anyone encountered the same issue ?

Thanks in advance, it would really help

Make sure you’re using the latest image. I’d suggest deleting that image and re-running `make pull`.

Hello emily,

I deleted current image and re-ran make pull (cpu and gpu) and I am still getting the same error message.

Thanks for raising this issue, there was indeed a dependency missing. This should now be fixed in the latest image.
