Dask-glm throws ContextualVersionConflict

[Shellcat-Zero]

After running either pip install dask-glm or conda install dask-glm the dask-glm-bench notebook fails to import the line from dask_glm.algorithms import proximal_grad, admm with a ContextualVersionConflict error:

ContextualVersionConflict: (multipledispatch 0.4.8 (/opt/anaconda/lib/python3.5/site-packages), Requirement.parse('multipledispatch>=0.4.9'), {'dask-glm'})

Both pip freeze and conda list show that multipledispatch version 0.4.9 is installed satisfying the dask-glm requirement, so I am not sure what to do here.

Your setuptools looks pretty old. Can you try upgrading that?

[Shellcat-Zero]

I presume they were automatically setup using dask-ec2 when I launched the EC2 cluster. Which setuptools are you referring to, or how do I update them?

[TomAugspurger]

Setuptools is a python packaging library: https://setuptools.readthedocs.io/en/latest/

pip install --upgrade setuptools should do it.

Ah yes, thanks, I thought you were referring to something more conda-specific. I'm going to re-create the cluster (I've already destroyed it) and try this again to verify.

Before relying too heavily on dask-ec2 you may want to read http://dask.pydata.org/en/latest/setup/cloud.html

I'll have a look, thanks.

Updating setuptools worked, thanks. Closing issue.
