Conda can solve a situation but mamba can’t:

Steps to reproduce:

• install wsl2 on windows

• install ubuntu 18.04

• install CUDA 10.2: * Download + install NVIDIA Driver: https://developer.nvidia.com/cuda/wsl/download Download CUDA+install version 10.2: https://docs.nvidia.com/cuda/wsl-user-guide/index.html#running-cuda

• install anaconda w/ python 3.7

• install mamba: conda install mamba -c conda-forge

• create virtualenv + install rdkit: mamba create -c rdkit -n my-rdkit-env rdkit --yes conda activate my-rdkit-env

• install RAPIDS: mamba install -c rapidsai -c nvidia -c conda-forge -c defaults rapids=0.14 python=3.7 cudatoolkit=10.2

• ERROR MESSAGE:
