Running python script with cmd file results in ImportError

Question

I have a python script named mesh_2.py

import sys
import os
import numpy as np
...

If I run it from Spyder with IPython console it works fine. But I want to run it with a cmd (start.cmd) file. It has the following content:

cmd /c activate py3.4 && mesh_2.py

As I try to run it I get:

ImportError: No module named numpy

I have Anadonda3 installed with a Python 3.4 environment named "py3.4". I am under Windows 7 64 bit.

If I open a cmd.exe myself and write:

activate py3.4
python
import numpy as np

Then everything is all right and I get no error messages. Does any of you have an idea what am I missing here?

Thank you in advance.

As I have written if I activate the environment manually then it does the import. So the package is installed in the virtual environment. — bdvd

activate the virtual enviroment, then run your program like python mesh_2.py — shivsn

The problem is that it needs to be started automatically. That is why I need the cmd script. — bdvd

Maybe formatting the command correctly. cmd /c activate py3.4 && mesh_2.py. If using quotes they go around items with spaces. See cmd /? for help on quotes. The first one is in the wrong position, it was optional anyway.. — user6017774

OK, you are right. I corrected it. But the error message is still the same. — bdvd

try replacing

cmd "/c activate py3.4 && mesh_2.py"

with

cmd "/c activate py3.4 && python mesh_2.py"
