How does one install/run mypyc on Anaconda/Spyder? The documentation (https://mypyc.readthedocs.io/en/latest/index.html#) does not address this.
Try installing a wheel from here: https://github.com/mypyc/mypy_mypyc-wheels/releases
Pick the one for your PC type (Windows, Mac, Linux) then open an Anaconda Command Prompt, go to where the file is downloaded and type: pip install filename.whl
For directions on how to use it read here: https://mypyc.readthedocs.io/en/latest/getting_started.html
Note compiling is done from the command prompt, not in Python. You should probably check out Pythran it's a more actively developed Python to native CPython module compiler, and it's pretty easy to use.
