To transfer a python project from one platform to another, we need to consider the dependencies.
Using requirements.txt can solve this problem.
Start a new conda enviroment:
conda create -n test_aeolus python=3.6
conda env list
conda activate test_aeolus
Try to run the project in this new environment, you will encontour many ModuleNotFoundError.
This is a “ping-pang” game, and install required packages in the brand-new environment by pip, until our package runs smooth. At this moment:
pip freeze > requirements.txt
cat requirements.txt
certifi==2020.12.5
cftime==1.4.1
netCDF4==1.5.6
numpy==1.19.5
pandas==1.1.5
python-dateutil==2.8.1
pytz==2021.1
scipy==1.5.4
six==1.15.0
wrapt==1.12.1
wrf-python==1.3.1
xarray==0.16.2
Test requirements.txt:
conda deactivate
conda create -n test_install python=3.6
conda activate test_install
pip install -r requirements.txt
python run.py
After testing, you may want to delete the test environment
conda remove -n test_install --all
