pygdf fails py.test

[abeduplaa]

I am re-installing pygdf on a linux ubuntu 16.04 instance with 1 NVIDIA K80 (Driver version 384.111). I started to have a pygdf 'invalid shared memory key' error and decided to reinstall pygdf. I am now trying to re-create an environment from notebook_py35.yml. The steps to remove and re-create the conda environment are shown below:
Steps taken to reinstall:

1. Remove pygdf conda envrionment (conda remove)
2. Did a conda clean to remove all from cache
3. re created pygdf environment
4. activated pygdf environment
5. Tried to run py.test but got the error 'no module named libgdf_cffi'

Not sure why the it won't pass py.test anymore.

The downloading of packages while creating pygdf env has no warning or error

I did the following and it works:

conda env create --name pygdf_notebook --file conda_environments/notebook_py35.yml
source activate pygdf_notebook
cd <source-root-of-pygdf>
pytest

Remove pygdf conda envrionment (conda remove)

To remove an environment, use conda env remove -n <env-name>.
conda remove removes a package from the current environment.

I wasn't able to get it to work, but I am now using an older commit with an older pymapd commit and it is now functioning properly

@abeduplaa , do you mean you are able to install the packages but the notebooks are not working?

Closing as seems to be a resolved environment issue.

@abeduplaa could cudf 0.2 work with old k80? I wish it can.

cuDF uses CUDA Unified Memory, which requires Pascal (Compute Capability 6.0+) or newer GPUs
