OMP: Error #15: Initializing libiomp5.dylib, but found libomp.dylib already initialized.

I created a new conda environment, installed pytorch, and then wanted to install spaCy. I ran 'conda install -c conda-forge spacy' which worked. However, when I ran 'python -m spacy download en_core_web_s', I got the following error:

OMP: Error #15: Initializing libiomp5.dylib, but found libomp.dylib already initialized. OMP: Hint This means that multiple copies of the OpenMP runtime have been linked into the program. That is dangerous, since it can degrade performance or cause incorrect results. The best thing to do is to ensure that only a single OpenMP runtime is linked into the process, e.g. by avoiding static linking of the OpenMP runtime in any library. As an unsafe, unsupported, undocumented workaround you can set the environment variable KMP_DUPLICATE_LIB_OK=TRUE to allow the program to continue to execute, but that may cause crashes or silently produce incorrect results. For more information, please see http://www.intel.com/software/products/support/. zsh: abort python -m spacy download en_core_web_s

I would prefer not to do the unsafe, unsupported, undocumented workaround, but resolve the issue properly.

SOLUTION:
conda uninstall intel-openmp -n base
conda install -c intel openmp -n myenv
