@fsaad @Schaechtle any thoughts on what i'm doing wrong?

[fsaad]

Hi @suhailshergill. Thank you for filing this issue. The issue is possibly due to a wrong version of conda.

Can you please follow the step-by-step instructions listed here? https://github.com/probcomp/iventure/blob/master/docs/conda.md

Let us know if encounter any issues.

@fsaad thanks for pointing me to those docs. Encountered failure at the second step. Looks like I need to enable some different channels (e.g. we need seaborn=0.7 and current channels don't list anything earlier than 0.8)

specifying conda-forge channel I was able to get most of the first set of dependencies for the environment except for pytest and numba. See output below:

@fsaad so I did some tinkering. After a few tries I was able to install bayeslite=0.3.1.1, and able to confirm by running the test suite (albeit 2 tests xfailed). A few things to note:

1. I had to modify some of the steps to get here.

2. Even if I had been able to follow the steps you shared, I would only have been able to get bayeslite=0.3.2 i.e., a version 2 years old (the latest stable is bayeslite=0.3.3 which is 4 months old). Could you share the recommended steps for bayeslite=0.3.3?

For the record, below are the steps I followed in order to install bayeslite=0.3.1.1:

1. I modified the pytest dependency in conda_python2.txt to pytest=2.9.* (I was unable to find version 2.8 in anaconda) and ran the following conda create -n probcomp --yes --file ./conda_python2.txt -c conda-forge -c numba -c sunpy python=2.7

2. I installed bayeslite by invoking conda install -c probcomp -c cidermole -c fritzo -c ursusest -c conda-forge bayeslite apsw in the newly created environment.

It was interesting that simply installing bayeslite did not pull in the apsw dependency. Is that as intended?

@fsaad made some more progress. So it seems the problematic packages (i.e., the packages that conda has a difficult time with) are bayeslite and loom. The others I was able to install via conda in a very straightforward manner (after including the extra channels you pointed to).

After that, I was able to install bayeslite by building from source via setup.py. I suspect a similar process might work for loom as well.

I am new to conda, but it seems the dependency tracking for bayeslite conda package is messed up. Hope this helps.
