How to install Pystan on RaspberryPi 4 Model B with 4GB RAM

[c0dbat]

Hi,

I was trying to install fbprophet on my rpi, one of the requirements for this module is pystan.

I had used

Code: Select all

pip3 install pystan

but the installation takes way too long and never finishes. I have even tried to install Pystan from source, the results are same.

Anyone have tried this before? Any help would me much appreciated!!
Thanks in Advance.
