Dear all,

I've installed pycalphad using conda, but when I do run_test.py, I got:

python run_test.py 

import: 'pycalphad'

Traceback (most recent call last):

Which versions of pycalphad, dask, distributed and xarray do you have?

You can check the versions with the
conda list

command.

Hmm. I'm not able to reproduce this with the following on macOS with Python 3.7


dask                      2.1.0                      py_0    conda-forge
dask-core                 2.1.0                      py_0    conda-forge
distributed               2.1.0                      py_0    conda-forge
pycalphad                 0.7.1.post2     py37h1de35cc_1000    conda-forge
xarray                    0.13.0                     py_0    conda-forge

Based on the traceback, it looks like it might be an xarray issue. Can you run the following successfully?

from xarray import Dataset, concat

Also, is it possible that you ran conda list from inside an environment with a different set of packages than the ones called by the base environment of Anaconda that you supplied in your traceback?

Yeah, it looks like an upstream issue at xarray. You can file an issue on the xarray GitHub: https://github.com/pydata/xarray/issues

In the meantime, you might be able to find success if you downgrade dask, dask-core, and distributed to a version less than 2, i.e.

conda install "dask<2" "distributed<2"

Thank you, Brandon,

Now I get this by running python run_test.py:

(base) Leis-Air-3:test leizhang$ python run_test.py 

import: 'pycalphad'

/Users/leizhang/anaconda3/lib/python3.7/site-packages/dask/config.py:168: YAMLLoadWarning: calling yaml.load() without Loader=... is deprecated, as the default Loader is unsafe. Please read https://msg.pyyaml.org/load for full details.

  data = yaml.load(f.read()) or {}

import: 'pycalphad.core'

import: 'pycalphad.io'

import: 'pycalphad.plot'


I guess it means OK now.

Best,
