Describe the bug
With the latest cdms2 from conda-forge, I'm getting an import error related to, which appears not to exist.

To Reproduce
Steps to reproduce the behavior:

conda create -y -n test -c conda-forge cdms2=3.1.4
conda activate test
python -c "import cdms2.tvariable"

The result is:

Expected behavior
Import should succeed.

Additional context
I think numpy.rank might work fine, and that was eliminated in the most recent release of numpy.

I can confirm that I do not see this issue with numpy<1.18:

conda create -y -n test -c conda-forge cdms2=3.1.4 numpy=1.17
conda activate test
python -c "import cdms2"

(No output)

fix was not correct -- working on the fix and adding a testcase.

@muryanto1, could you explain what was wrong with the fix?

By the way, my test environment is still picking up cdms2 build 4 (rather than build 7 that we just merged) but I think that's because of a different dependency not being up-to-date with conda-forge pinnings. So as far as I know, conda-forge/cdms2-feedstock#47 should have fixed things from my perspective. But maybe there's something more subtle?

As we discussed, the issue is that numpy.rank isn't the right replacement, and numpy.ndims is actually what's needed.

It's odd to me that the old is equivalent to numpy.ndims but whatever works...

muryanto1 commented Feb 5, 2020

@xylar correct, I am replacing calls to numpy.rank() with numpy.ndims(), @jasonb5 helped me with the fix. we are testing the fix.
