Error in subprocess python

In Linux, if I execute this command in the terminal :

ipython  '/media/folder1/myscript.py'

it works. But, If I execute in IPython terminal :

import subprocess
cmd_list= ["ipython", '/media/folder1/myscript.py' ]
proc= subprocess.Popen(cmd_list)

I have this error :

cmd_list= ["ipython", filescript]
proc= subprocess.Popen(cmd_list)
Traceback (most recent call last):

  File "<ipython-input-47-66f9b0f2ed3f>", line 2, in <module>
    proc= subprocess.Popen(cmd_list)

  File "/home/linux1/anaconda2/lib/python2.7/subprocess.py", line 711, in __init__
    errread, errwrite)

  File "/home/linux1/anaconda2/lib/python2.7/subprocess.py", line 1343, in _execute_child
    raise child_exception
OSError: [Errno 2] No such file or directory

Why sub-process cannot execute this terminal command ?

You need to specify the full path for ipython. Type:

which ipython

in a terminal and use the path it tells you with subprocess:

cmd_list= ["/path/from/which/ipython", '/media/folder1/myscript.py']

Alternatively, you can try with shell=True:

subprocess.Popen(cmd_list, shell=True)

This might not be recommended, depending on your usage.
