Has anyone encountered this? Solutions?
Anderson Banihirwe (Jun 09 2020 at 13:42):I am on somewhat up-to-date versions of cartopy and proj and things seem to work fine ( I tested the import)
$ conda list cartopy # packages in environment at /glade/work/abanihi/softwares/miniconda3/envs/analysis: # # Name Version Build Channel cartopy 0.18.0 py37h4b180d9_0 conda-forge abanihi at casper26 in ~ $ conda list proj # packages in environment at /glade/work/abanihi/softwares/miniconda3/envs/analysis: # # Name Version Build Channel proj 7.0.0 h966b41f_4 conda-forge pyproj 2.6.1.post1 py37h34dd122_0 conda-forge
I am curious... Did you pin your proj and pyproj versions? They are a little outdated:
abanihi at casper26 in ~ $ conda list cartopy # packages in environment at /glade/work/mclong/miniconda3/envs/krill: # # Name Version Build Channel cartopy 0.18.0 py37h4b180d9_0 conda-forge abanihi at casper26 in ~ $ conda list proj # packages in environment at /glade/work/mclong/miniconda3/envs/krill: # # Name Version Build Channel proj 6.3.1 hc80f0dc_1 conda-forge pyproj 2.5.0 py37he3cd046_1 conda-forge
Matt Long (Jun 09 2020 at 13:46):no, I did not pin my proj and pyproj versions, but I bet that this is the problem. I don't include them in my specific list of dependencies.
Matt Long (Jun 09 2020 at 13:48):Here's the environment: https://github.com/matt-long/krill-cesm-le/blob/master/environment/environment.yml
Matt Long (Jun 09 2020 at 13:48):Can you suggest a modification?
Anderson Banihirwe (Jun 09 2020 at 13:48):Can you suggest a modification?
I am looking into it
Anderson Banihirwe (Jun 09 2020 at 13:49):i am inspecting the environment to see what packages may be restricting pyproj and proj to be updated
Matt Long (Jun 09 2020 at 13:50):many thanks!
Anderson Banihirwe (Jun 09 2020 at 13:51):Anytime!
Anderson Banihirwe (Jun 09 2020 at 13:51):Are you using this environment file: https://github.com/matt-long/krill-cesm-le/blob/master/environment/environment.yml?
Matt Long (Jun 09 2020 at 13:52):yes
Anderson Banihirwe (Jun 09 2020 at 14:02):I happened to have a krill environment. I tried updating it with conda env update -f environment/environment.yml and I noticed that proj and pyproj versions didn't change i.e. before and after the update:
$ conda list proj # packages in environment at /glade/work/abanihi/softwares/miniconda3/envs/krill: # # Name Version Build Channel proj 7.0.0 h966b41f_3 conda-forge pyproj 2.6.0 py37h34dd122_1 conda-forge
I'd recommend updating the environment file with the following:
- cartopy >= 0.18.0 - proj >= 7.0.0 - pyproj >= 2.6.0
Matt Long (Jun 09 2020 at 14:05):thanks, I'll try it
Matt Long (Jun 09 2020 at 14:58):this seems to have fixed my import error
Matt Long (Jun 09 2020 at 14:58):thanks!
Anderson Banihirwe (Jun 09 2020 at 15:00):Awesome :tada:
Mira Berdahl (Jan 18 2024 at 23:13):@Matt Long , looks like this happened a while ago for you, but do you recall how you resolved it? This exact thing just happened to me.

Drew Camron (Jan 19 2024 at 20:41):Something like this is usually an environment conflict or other mismatch of dependencies. Are you using conda? Can you activate the environment and share the output of conda list? Sometimes a conda update --all might get you there, depending on how complex your environment is.
