Hi @tangzhenyu , thanks for letting us know about this issue, sorry for the delayed response. Can you let us know a bit about your environment?

Specifically, which release/build of Julian are you using and on what system? Did you build Julia from source or did you grab a binary? It seems that there is some issue here with Julia seeing the BLAS libraries. Perhaps your current build of Julia is missing s BLAS distribution?

@eric-tramel ,very thanks for your reminder.Actually,as you are saying,it was lacking of BLAS libraries.After installed this library,the code works.Thanks a lot again.
