Executing a python script from scala giving error while running the same script from the command line does NOT

Question

This is my python script:

!/usr/bin/python
   import sys
   import magic
   m=magic.from_file('<file with absolute path goes here>')
   print(m)

On running this from the command line:

$ python script.py
Microsoft Word 2007+

results in the output of the TYPE of the document that file is. Using python-magic.

Now running the same script from scala using below code:

import sys.process._
def compWithLibmagic(){
    val result = "python /script.py" !
}

throws the below error:

Traceback (most recent call last):
File "script.py", line 3, in <module>
import magic
ImportError: No module named magic

PS: I have both python 2.7 and python 3.6 installed on my machine and running the script using any of them from the command line runs just fine so I guess both of them are bundled with the MAGIC packages correctly.

Would highly appreciate any kind of help.

Answer 1

I will try to answer my own question in the best possible way.

While trying to execute the script.py from the command line using python compiler python2.7 was being used and when I tried to invoke the same script.py from the scala compiler using

import sys.process._
def compWithLibmagic(){
    val result = "python /script.py" !
}

it was using python3 which was getting unnoticed. It took me a couple of days to actually figure this thing out and finally I removed all the python2.7 and python3 libraries and installed python 2.7 again and it worked like a charm.
