I created a conda environment - testenv2 - installed python/numpy/pandas. Added it as the interpreter in Eclipse project settings and using it to run my test python script.
Add CONDA_DLL_SEARCH_MODIFICATION_ENABLE=1 to your environment variables.
CONDA_DLL_SEARCH_MODIFICATION_ENABLE=1
For VSCode, either an .env file in your workspace folder or "env" key in launch.json should do the trick.
.env
"env"
