[HiloadProgrammer]

In Dockerfile.jupyterhub the line RUN /opt/conda/bin/conda install -yq psycopg2=2.7 updates the python version from 3.6.6 to 3.7.*. Therefore you will get a similar error as Conda #9672: No module named ‘conda’ . To fix this issue I added the line RUN echo "python 3.6.*" > /opt/conda/conda-meta/pinned before I installed psycopg2 to pin the python version.
