OMP: Error #15: Initializing libomp.dylib, but found libiomp5.dylib already initialized multiple copies of the OpenMP runtime have been linked into the program #135

when I use somoclu on ubuntu, there is no problem and perform perfectly with 100% cpu usage, but when I do the same experiment on Macbookpro with spyder IDE, it tells me that "OMP: Error #15: Initializing libomp.dylib, but found libiomp5.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.

can you tell me how to fix the problem?

Are you using the conda forge version?

If you're on MacOS , then do the following to solve the issue:

import os
os.environ['KMP_DUPLICATE_LIB_OK']='True'
