Transferring Conda environments across platforms

I downloaded Anaconda and started using it on my Mac but now I am switching laptops. I will be using a Windows laptop now and I need to transfer my environments to my new laptop. How best can I do this?

I am using Python version 3.8 and was using Jupyter notebooks to run my code. But if I simply try to run the notebook on my Windows laptop I am getting one error after another (because I don't have the packages installed). Installing them one by one will take time and I don't even remember most of what I installed.

If you are working across platforms (osx-64 -> win-64) you'll need to be minimal about what packages you export from the existing environment. While Conda does have a recommended intra-platform procedure for exactly recreating environments, it does not directly translate to the cross-platform situation. Instead, try using:

conda env export --from-history > environment.yml

and then, on the new computer,

conda env create -f environment.yml

This will only export the packages that you have explicitly specified to be in the environment at some point (e.g., using conda install foo). Dependencies will be resolved automatically on the new system. This does not guarantee there still won't be packages that aren't available on Windows, but they should be less frequent and easier to resolve manually (typically by removing them from the YAML or adjusting versions).
