670755564 MDU6SXNzdWU2NzA3NTU1NjQ= 4294 PyInstaller executable which packages xarray throws an error when executable is run canol 60890 closed 0     2 2020-08-01T10:47:30Z 2020-08-02T07:05:15Z 2020-08-02T07:05:15Z NONE      

This might be a problem related to PyInstaller, but we are packaging a lot of packages like numpy, pandas, matplotlib, scipy, PySide2; and xarray is the only one that causes an error, so I wanted to first open the ticket here.

What happened:

When I run an executable that PyInstaller creates out of a script that uses xarray >= 0.14, I get this error (using xarray 0.13 does not cause this error):

Minimal Complete Verifiable Example:

Make sure xarray and PyInstaller is installed on your environment.

Create example.py:

```import numpy as np import xarray as xr

a = xr.DataArray(np.zeros(10)) print(a) ``` on console run this command:

pyinstaller example.py

It will create an executable example.exe in a new dist folder. Run that executable in a command prompt to be able to see the error message.

Anything else we need to know?:

The error does not happen with xarray version 0.13.

Environment:

xr.show_versions() output:
