Error installing scipy

[YungAlfa]

Very new to this but I am trying to install scipy as a part of quantstats and I am receiving an error message saying requirements to build wheel did not run successfully. Here is the code:

  ../../meson.build:49:0: ERROR: Unknown compiler(s): [['gfortran'], ['flang'], ['nvfortran'], ['pgfortran'], ['ifort'], ['g95']]
  The following exception(s) were encountered:

I am using pip3 on macOS Big Sur. Any solutions to this would be much appreciated, thanks.

Hi, I think you reported this to the wrong place, this is for issues installing PocketSphinx, not SciPy, and I don't know what quantstats is either.
