ImportError: numpy.core.multiarray failed to import

[Mrvy29]

Hi Antoine !

I am really enjoying working with this package , thank you ! I've been using it successfully during the last year and have also started using it with google colab.

I've recently encountered a RuntimeError: module compiled against API version 0x10 but this version of numpy is 0xf, it seems some dependencies don't work anymore specifically ImportError: numpy.core.multiarray failed to import which never happened before. I tried to solve it independently but haven't managed to get anywhere and would appreciate your help. I want to preface that this issue is only relevent with google colab as it requires new installs and doesn't (to my knowledge) allow packages previously installed to be stored for longer term use.

Code for reproduction

# !pip install pyEddyTracker

Really appreciate your support !

It's looks like a numpy version incompatible with polygon

[berzinastella]

Hi, Merav @Mrvy29 , Did you manage to fix your issue? I'm having the same issue and I am wondering if you figured out which numpy is compatible?

Best, Stella

How did you install py eddy tracker?

Hi, Merav @Mrvy29 , Did you manage to fix your issue? I'm having the same issue and I am wondering if you figured out which numpy is compatible? Best, Stella

How did you install py eddy tracker?

I got it working by having a 3.9 python version, numpy 1.22.4 and netCDF4 1.6.0, matlpotlib 3.7.1. For higher versions of anything it did not work for me at all. Installed pyeddytracker by pip installing.

[AntSimi]

It's a new environement?

[berzinastella]

It's a new environement?

Yes, i created a new environment for this

[AntSimi]

before to install numpy maybe try to install polygon3

[Mrvy29]

Hi @berzinastella @AntSimi , I'm sorry it took me so long to get back to this issue. Originally I had resorted to working on my local runtime exclusively because I could not solve the issue. I will however try to install polygon3 before numpy, because in my experience the numba and numpy dependencies were already not compatible hence the py-eddy-tracker wasn't even imported I will update.

[Mrvy29]

Nope , this hasn't solved this issue. here is my code - just to reiterate , using google Colab , py eddy tracker (that was updated probably) does not work properly because of dependency issues. M

An update about this issue, using brew and poetry and a pyenv, using python 3.10.13 made the imports all possible without raising API error or grid issues. Nonetheless eddy detection doesn't work properly using the final : a, c = g.eddy_identification("adt", "u", "v", date, 0.002, shape_error=55) see issue #227
