My research lab and I use a centralized install of miniconda (not installed via root). We've been using conda <v4.4 due to issues with installing certain software for conda >=4.4. In order to start the transition to >4.4, I created a 2nd centralized install of miniconda. Installing this 2nd version of conda seems to have broken nb_conda for all of our Jupyter notebooks. For creating new notebooks, we now only have two options: "Python 3" or "R". Previously, we could select from ~15 different conda environments. When I click on the "conda" table in Jupyter, I get an error, and this is reported on the command line:

[E 13:45:08.273 NotebookApp] [nb_conda_kernels] couldn't call conda:
Why did a 2nd conda install affect nb_conda? Isn't everything contained in the conda install directory? Any ideas on how I revert back? Our whole research group of ~20 people now do not have access to the conda environments in Jupyter.
