OpenBLAS Warning

Open qazzaq1017 opened this issue 5 years ago • 6 comments

I got endless OpenBLAS Warning when call show.velocity.on.embedding.cor, and no result after over half an hour. My R is installed with conda venv. Can I fix this with conda command?

This is bad. I tried hours. No solution was helpful.

Same warning message. Any ideas of how long this step takes? or something is going wrong? No results after running for a few hours on 20k cells

The underlying operational logic cores of OPENBLAS is 1，so before you use R to caleculate，execute this command in your terminal export OMP_NUM_THREADS=1 The others method of resolution is that fix the number of 'n.cores' to 1https://github.com/velocyto-team/velocyto.R/issues/131#issuecomment-848391934
