[PYTHON] I stumbled when I tried to install Basemap, so a memorandum
After browsing at the bookstore, Basemap (A module that allows you to easily plot a map with python. It is very useful when you want to visualize data on a map.) I went back and installed it immediately because there was something that looked cool.
You can draw a cool map with the following simple code. I stumbled upon the installation, so a memo as a memorandum.
import matplotlib.pyplot as plt
from mpl_toolkits.basemap import Basemap
%matplotlib inline
m = Basemap()
m.bluemarble()
Execution environment
Python 3.7.6 macOS Mojave 10.14.6 Jupyter Notebook
Installation method
At first.
$ brew install geos
Suddenly stumble below.
$ wget https://jaist.dl.sourceforge.net/project/matplotlib/matplotlib-toolkits/basemap-1.0.7/basemap-1.0.7.tar.gz
The following error was thrown. Hmm. .. Apparently there is a problem with wget.
dyld: Library not loaded: /usr/local/opt/openssl/lib/libssl.1.0.0.dylib
Referenced from: /usr/local/bin/wget
Reason: image not found
zsh: abort wget
Check with which. It seems that wget is installed.
$ which wget
/usr/local/bin/wget
Try upgrading wget.
$ brew upgrade wget
==> Upgrading 1 outdated package:
wget 1.20.3 -> 1.20.3_2
The upgrade went well, so I tried again.
$ wget https://jaist.dl.sourceforge.net/project/matplotlib/matplotlib-toolkits/basemap-1.0.7/basemap-1.0.7.tar.gz
Download failed.

Then execute the following command.
$ tar zxvf basemap-1.0.7.tar.gz
$ cd basemap-1.0.7
$ python setup.py install
I got an error after python setup.py install. .. It's long.
ModuleNotFoundError: No module named 'numpy.random.mtrand'
This time there seems to be a problem with numpy, so uninstall → install.
$ pip3 uninstall numpy
$ pip3 install numpy
After reinstalling, do the following again.
$ python setup.py install
It went well! !! !!
However, when I actually tried to use it with jupyter, I got an error.
ImportError: No module named 'mpl_toolkits.basemap'
If you are looking for various things, you should use this command.
$ pip3 install https://github.com/matplotlib/basemap/archive/master.zip
However, it is not a zip file. Error.
zipfile.BadZipFile: File is not a zip file
Executed because it is possible to drop netCDF4.
$ pip3 install netCDF4
I finally got it! !!
