"sqrt" is not a known member of module (numpy)

See original GitHub issue

When running the command-line pyright on

import numpy

numpy.sqrt(5.0)

I correctly get

No configuration file found.
stubPath /tmp/typings is not a valid directory.
Assuming Python platform Linux
Searching for source files
Found 1 source file
0 errors, 0 warnings, 0 infos

When using coc-pyright, I get

[Pyright (reportGeneralTypeIssues)] [E] "sqrt" is not a known member of module

A bug?

Indeed, this is fixed in numpy master and will be part of the next release. https://numpy.org/devdocs/release/1.20.0-notes.html#numpy-is-now-typed

@nschloe

If you want to get similar error results, try to run pyright --lib. (If you don’t have stub installed)

Until numpy 1.20 is released, it’s best to use a third-party stub. (e.g. data-science-types) REF: https://github.com/numpy/numpy/issues/17826#issuecomment-731862373
