Can't figure out what Dask wants in terms of msgpack/msgpack-python

[rjurney]

I can't figure out what Dask wants in terms of msgpack/msgpack-python and I've read all about it. I am trying to run it in distributed mode, but my workers die. I fixed this once but lost the solution and the default setup doesn't work so I have to run workers manually.

The command I run:

nohup dask-scheduler &
dask-worker --nprocs 2 --nthreads 2 127.0.0.1:8786

What happened: I get this result:

distributed.worker - INFO -       Start worker at:      tcp://127.0.0.1:38591

What you expected to happen:

I expect the workers to live. Instead they die. I can't figure out what Dask wants in terms of msgpack.

Anything else we need to know?:

Can someone please tell me how to setup my environment in a way Dask likes regarding msgpack/msgpack-python? I first used pip to install both then found a bug fix that said use conda so I did. That did not help.

Environment:

• Dask version:

dask==2.14.0
dask-glm==0.2.0
dask-ml==1.5.0

• Python version: Python 3.6.10 :: Anaconda, Inc.
• Operating System: Ubuntu 18.04 Amazon Deep Learning AMI

Hi @rjurney !

Oof, that sounds frustrating. Dask requries msgpack-python >= 0.6.0. It looks like you have version 0.5. A quick conda install dask should bring you up to a sensible configuration.

I'm actually quite surprised that conda let you have that version of msgpack-python installed. We currently pin to >=0.6.0 in the conda recipe.

[rjurney]

@mrocklin The latest version of msgpack-python on PyPi is 0.5.6. See: https://pypi.org/project/msgpack-python/#files

I see newer version here though: https://anaconda.org/anaconda/msgpack-python/files

[mrocklin]

If you're downloading from PyPI then you want the msgpack package: https://pypi.org/project/msgpack/ If you're downloading from conda-forge there is a conflict because there are many msgpack packages. The python one is called msgpack-python. Regardless, if you follow the install instructions at https://docs.dask.org/en/latest/install.html then your package manager (pip or conda) should ensure that you have the right packages necessary to run Dask.

@mrocklin The instructions assume a good version gets installed as a dependency of Dask and it does not. They don't speak as to msgpack.

I have msgpack==1.0.0 after running conda install -c anaconda "msgpack-python" and I get this error:

I can't figure out what Dask wants from me, it makes no sense. I did what I'm supposed to do and the right package is installed.

@mrocklin I removed all msgpack and msgpack-python modules and installed msgpack from pip.

pip freeze shows: msgpack==1.0.0 and cloudpickle==1.3.0

Now I get this error:

You shouldn't have to explicitly install msgpack. Can you verify that you've done the instructions in https://docs.dask.org/en/latest/install.html . Your package manager will handle this for you.

And I'd recommend creating a clean conda or virtual environment to test out the instructions at https://docs.dask.org/en/latest/install.html. Pip and sometimes conda can struggle to install packages into currently broken environments. On Tue, Jun 9, 2020 at 10:16 PM Matthew Rocklin <notifications@github.com> wrote:

@TomAugspurger I got it to work in a clean environment, thanks.

[sravzpublic]

I had these package preinstalled before Dask and distributed where installed:
pip3 freeze | grep msgpack
msgpack==1.0.2
msgpack-python==0.5.6

Dask distributed package pulls in msg pack. To ensure scheduler and workers have same pip packages. Un install msg pack and allow distributed install it.

pip uninstall msgpack-python
pip uninstall msgpack
pip uninstall "dask[complete]"
pip uninstall "distributed"

Install dask and distributed only:
pip install --upgrade --no-deps --force-reinstall "dask[complete]"
pip install "distributed"

Distributed will pull msgpack
