Constraints on installing pip packages on workers?

[Tushar-N]

I'm trying to add this package as a requirement for evaluation. I uncommented the code here that calls pip install <package>but I get the following error on the worker log when I try and submit. Are there some packages that can't be installed this way? Other packages install fine (e.g., shapely-1.7.1 from the example script)
