Failed to load Earth after having successfully installed py-earth... #187

Open jiapei100 opened 6 years ago

ERROR messages:

>>> from pyearth import Earth
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>

    from ._forward import ForwardPasser
ModuleNotFoundError: No module named 'pyearth._forward'

Any suggestions? Pei

@jiapei100 This seems to happen when people try to run python from within the py-earth source directory after installing. Could that be the problem in your case?

@mk123qwe Sorry for the delay. I believe you are dealing with the same problem as @jiapei100. If you run Python from a different directory it should solve your problem.
