Part of Antartica is missing...

[auroralin0408]

I was drawing regions around the Antartica, and found that m.fillcontinents somehow failed to draw continents. Then I tried this, and the result was obviously wrong...

I am using Python3.8 and basemap1.2.2 Thanks for any answer :)

Hi @auroralin0408! This was a known issue that was fixed in version 1.3.5. You can try upgrading to this newer version.

What is your environment? If using a simple Python installation wih pip as package manager, it should be enough to type:

python -m pip install basemap --upgrade

There are also conda packages for basemap version 1.3.5 in case that you are using conda.

[auroralin0408]

Thanks for your quick reply ! I'm using conda. I tried to upgrade, but it failed.

[molinav]

Unfortunately, I think I cannot be of more help. I have just tried this with a clean Python 3.8 environment on Windows miniforge3 and it works as expected:

(base) C:\Users\vic>conda activate py38

(py38) C:\Users\vic>conda install -c conda-forge basemap=1.3.5

The error that you get is related to the process of downloading packages from the repository, so I guess it is a broader problem in your environment and not related to basemap itself. Have you tried to install other conda packages and see if this SSL error also appears?

[auroralin0408]

I just built up a new virtual env to install basemap, and other conda pkgs can be downloaded and installed successfully. When I use conda install basemap, only version 1.3.4 will be installed, even though the output of conda search basemap contains 1.3.5 and 1.3.6.

However when I ran conda install -c conda-forge basemap=1.3.5, it stuck here without exact output:

Besides, on MacOS, the output of conda search basemap only contains 1.3.2, and can't find proper pkg to install.

[auroralin0408]

Hi, I tried to install matplotlib and basemap at first, then it worked. I can use basemap 1.3.6 on Windows. But the same solution can't work on MacOS. And I also tried other commands on https://anaconda.org/conda-forge/basemap, it got the same error.

[molinav]

Hi @auroralin0408, I am happy to hear that it finally worked on Windows!

For MacOS, are you using a MacOS on M1 processor? As far as I know, the current conda-forge recipe for basemap only creates packages for MacOS on Intel processors (see open PR in https://github.com/conda-forge/basemap-feedstock/pull/108).

[auroralin0408]

Ok, I see. It's enough to run codes on Windows. Thanks a lot !!!

[molinav]

Thanks for your undestanding, @auroralin0408. At some point it would be nice to also support M1 in conda-forge, it is just that I didn't find the time to try out, and also I do not have an M1 to play around myself. But hopefully in the future it will also be supported.
