matplotlib cannot be upgraded due to error in basemap

[Joern Ungermann]

basemap crashes with current matplotlib due to the use of the deprecated dedent function.

‌

See

https://github.com/matplotlib/basemap/issues/495

Current version fixing solves this for now. Not a long term solution, obviously.

matplotlib 3.2.2 shows a change in cbook needed

from matplotlib import cbook, figure

ImportError: cannot import name 'cbook' from 'matplotlib' (unknown location)

[Reimar Bauer]

@Joern Ungermann can we go to 3.1.3 ?

‌

the 3.2.3 seems to need refactoring for cbook calls

‌

[Joern Ungermann]

I do not see the same problem for matplotlib 3.2.2

I can import cbook.

>>> import matplotlib.cbook

3.2.2

matplotlib 3.3 also has a cbook. see https://matplotlib.org/3.3.1/api/cbook_api.html

In [1]: import matplotlib.cbook

In [2]: matplotlib.__version__
Out[2]: '3.3.1'

What is exactly the problem, and when and where does it occur?

[Joern Ungermann]

The error was fixed in basemap, btw, so due to the original error the issue should be closeable, though. Due to the version number nightmare, upgrading an existing conda might not work reliably, though.

[Reimar Bauer]

I flipped the version in both direction, may be that made it look broken to me.

starting msui and it shows a missing dependency.
