   test.py
   import numpy
   import sklearn

   def a():
   return

   main.go
   t := python.PyImport_ImportModule("test")

   t actually is nil

   Just remove import numpy and sklearn from test.py, then it works.

   you're probably mixing python libraries (i.e.: trying to import numpy from anaconda while you compiled go-python against another python2 interpreter.)

   try this program to display the error:

   package main
   
   import (
   	"log"
   
   	"github.com/sbinet/go-python"
   )
   
   func init() {
   	err := python.Initialize()
   	if err != nil {
   		panic(err.Error())
   	}
   }
   
   func main() {
   	m := python.PyImport_ImportModule("numpy")
   	if m == nil {
   		python.PyErr_Print()
   		log.Fatalf("could not import numpy")
   	}
   	m.DecRef()
   }
