Can I please get some help what should I do next ?  I was always getting error for Plot function.

Thanks,

Are your packages all up to date? Does Pkg.status() show any local modifications? This sounds like https://github.com/stevengj/PyPlot.jl/issues/140, do any of the workarounds suggested there or in the linked PyCall issues help? Are you using the Linux tarball download of Julia?

See https://github.com/stevengj/PyCall.jl/issues/65

You may just have an old copy of `libopenblas.so` lying around from an earlier Julia version.
