EOF error when I try to use 'expect' function from'Pexpect'

I'm trying to automate the process of switch between networks in "Cisco AnyConnect", but my code always is terminated with an 'EOF error'.
I've tried a search in API doc for some help and used different expressions like: "Network", "Network:" or "Network.*".
from pexpect import popen_spawn
import pexpect
vpnui = pexpect.popen_spawn.PopenSpawn(r'C:\Program Files (x86)\Cisco\Cisco AnyConnect Secure Mobility Client\vpnui.exe', maxread=2000)
vpnui.expect('Network:')
vpnui.sendline('SomeNetwork')
The error:

Can not import theano after installation windows 10

I've still not been able to resolve this problem, after working on it for a week.
I'm thinking of giving up and just running theano on a virutal machine; there just doesn't seem to be any support out there for Windows 10!
Or am I wrong; is there an easy fix to this?

TypeError: can't concat bytes to str
Um, can't concat bytes to str? What does this mean?

The error you are experiencing appears to result from another sub-process utilizing the same resources as the script you are attempting to write. Although it sounds trivial, I would recommend making sure that you have admin privileges, or at least privileges to the desired resources, and/or restart your computer to kill the sub-process using that module. You could also look in the task manager and kill any/all other processes using python, but that might take longer.
(This may be the program using the "resource" try_march_3v6ffkv9.exe)

KeyError when assigning ''praw.Reddit'' to variable

I could successfully connect to reddit's servers with oauth2 some time ago, but when running my script just now, I get a KeyError followed by a NoSectionError. Code is below followed by exceptions, (The code has been reduced to its essentials).
import praw

Error while loading two dot files in python

How can I load two separate dot.files in python.
I was trying like this but I got an error.

Why I am getting file not found exception while copying file on HDFS using Pydoop?

My Python code using Pydoop API is show below. I have a text file /home/progen/test.txt. While running the script to copy this file to HDFS, I am getting an error.
import pydoop.hdfs as hdfs
local_path = '/home/progen/test.txt'
hdfs_path = '/spark_user/'
host = 'master'
port = 9000
hdfsobj = hdfs.hdfs(host, port, user='spark', groups=['supergroup'])
hdfsobj.copy(local_path, hdfsobj, hdfs_path)
I am getting the Error: "File does no exist"
