Problem with TMVAClassifier

[tlikhomanenko]

Can you run in the same notebook the following code:

import tempfile
import os
name = tempfile.mkdtemp(dir=os.getcwd())

and then in other cell:

!cd $name

I want to check that process has access to the temporary folder.

The result is:
/bin/sh: 1: cd: can't cd to /home/artem/Documents/IPython

[tlikhomanenko]

Run:

!ls -la /home/artem/Documents/

!whoami

[HolyBayes]

ls -la /home/artem/Documents/ works OK. IPython was launched from admin user, but admin not in sudo group.

[tlikhomanenko]

Write output of ls -la /home/artem/Documents/ to see the rights of /home/artem/Documents/IPython

The problem is your path: IPython Notebooks/. It contains space, that is why command 'cd {folder}' doesn't work, and weights is created outside the temp folder.

Thanks, will fix this error in next release.

At this moment, rename this folder without spaces, or move starter kit notebooks into other place.

[HolyBayes]

Ok, thanks!
