conda env and openexr install error

[etaoxing]

When I tried to create the conda env inside the flingbot Docker instance, I got this error:

    Running setup.py install for openexr: started
    Running setup.py install for openexr: finished with status 'error'

Pip subprocess error:

CondaEnvException: Pip failed

Installing the "libopenexr-dev" package inside the Docker instance as suggested here, and then creating the conda environment fixes this issue.

I solved this by running conda install -c conda-forge openexr-python

conda install -c conda-forge openexr-python
