## Mac OMP Errors
If you encounter the error `OMP: Error #15: Initializing libomp.dylib, but found libomp.dylib already initialized.` it is most likely
that you are trying to use the `sasktran2` wheel package (through `pip`) inside a conda environment.  The best solution
is to instead install the conda-forge package.

Alternatively, if that is not possible, or you are getting the error outside of a conda environment, you can try adding

```{code}
import os

os.environ["KMP_DUPLICATE_LIB_OK"] = "TRUE"
```

To the top of your script.
