conda environment file to install different packages from different channels
Background
yfinance library is the easiest and fastest way to download historical stock prices. Asof 2023-05-20, it is not available in the defaults channel. But it is available in the conda-forge channel.
Task
The goal here is to pull the yfinance package from conda-forge but everything else from the defaults channel.
Solution
% cat env_test_yfinance.yml | stuff.py name: test_yfinance channels: - defaults dependencies: - python=3.11 - conda-forge::yfinance
where stuff.py is a python script to strip out the comments. It can be downloaded from https://github.com/KamarajuKusumanchi/rutils/blob/master/python3/stuff.py
Create the environment
% conda env create -f ./env_test_yfinance.yml
Evidence
yfinance is downloaded from conda-forge.
% conda list -n test_yfinance | grep conda-forge multitasking 0.0.9 pyhd8ed1ab_0 conda-forge yfinance 0.2.18 pyhd8ed1ab_0 conda-forge
python is downloaded from the defaults channel
% conda list -n test_yfinance | grep "python" python 3.11.3 h7a1cb2a_0 python-dateutil 2.8.2 pyhd3eb1b0_0
