In my Python script I am trying to set some phone settings through Marionette driver. I am importing the following:
from marionette_driver import By
from marionette_driver import Wait
from marionette import Marionette
Then I am attempting to open a client session with the device:
client = Marionette('localhost', port=2828)
client.start_session()
However, I am receiving UnknownCommandException:
Traceback (most recent call last):
File "xyz.py", line 30, in <module>
client.start_session()

marionette_driver.errors.UnknownCommandException: WebDriver:NewSession
FYI, I am using marionette-driver 1.1.1
Any suggestion regarding resolving this issue will be much appreciated.
Edit on 10/26/2018
It is returning a different error message now:

ImportError: No module named marionette_test
This is probably due to an outdated driver as answered here: WebDriver Error New Session
You can download the lastest from the Github Mozilla Repo.
If it is not Repo relate then it could be because .pyc files linger and python tries to use them first before recompiling.
Basically you would find the relate .pyc files and remove then so the source is recompiled. Check this open bug for more info.
Thank you. Good day.

I am using Paraview 4.0.1 under Ubuntu 14.04 LTS.
But I guess the answer to this question does not necessarily requires knowledge specific to Paraview python.
When I load a python prompt at the command line everything "works well":
$ pvpython
Python 2.7.6 (default, Oct 26 2016, 20:33:43)
[GCC 4.8.4] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from paraview.simple import *
paraview version 4.0.1
>>>
But when I load the python shell within the GUI, from paraview.simple import * fails, either when automatically (at startup) or explicitly imported:
Python 2.7.6 (default, Oct 26 2016, 20:33:43)

How can I trace the different sequence of steps taken by each mode of loading a python shell, so as to identify the source of error?
In addition to this manifestation, I found two other differences:
In the command prompt, from paraview.simple import * is not executed automatically, while in the GUI it is. Where is this set?
In the command prompt, having set PYTHONSTARTUP=${HOME}/.pythonrc, which sets import readline, rlcompleter (actually, within a try-except construct), allows for tab completion.
In the GUI, .pythonrc is not read. Why is this? How can I tell the filename which would be read upon startup if it exists?
I have found one option which gives some information, I do not know if it is the only/best one.
Setting
$ export PYTHONVERBOSE=2
(or a different integer for verbosity level [1]) gives a lot of info.
Still, I couldn't find the source of error...
I thought, I broke Eclipse by renaming one of my source file logging.py, I quickly changed the name to something else but Eclipse cannot find the original python standard file ... I reinstalled my Anaconda install but it did not correct the problem ... and I later discovered it was likely a Python problem (see Edit 1)
When I ask Eclipse to find or open the file from the 'import logging' line, it seems it cannot find it ...
Any idea to correct this problem without reinstalling Eclipse?

The problem happens with the executable generated by pyinstaller too ?! :

First, define modules path, where built-in module logging is placed:
user#host:$ python

Type "help", "copyright", "credits" or "license" for more information.
>>> import sys
>>> sys.path
['/usr/lib/python2.7', ... ]
Second, ensure that there is a logging package. In my OS i have /usr/lib/python2.7/logging. I think you renamed the package accidentally; If so, rename it back.
I came across a very similar problem. The error I was receiving was: "AttributeError: ‘flask.logging’ object has no attribute ‘getLogger’". And the solution was downgrade the package Flask (settings -> project -> project interpreter).
Sorry, I solved it myself.
I thought Eclipse delete the .pyc files when I told it to clean the project, but it is not how it works apparently, So after 2 reinstalls of anaconda and configuration tweaks for this project (I have others ...), I finally remembered to check that ... the .pyc for the file was still there with the old name 'logging.pyc' ... thanks Eclipse as always, for wasting my time with your quirks!
I am working on a project which utilizes the wbdata package for python, which is a wrapper for the world bank api. It was working fine until I made what I have guessed to be to large of a request of data, which I had to cancel, and now the package won't even load when I use the import wbdata function.

Use ipython's magic %debug and check what cachefile's file name is. If it's a regular file, name should be accessible as cachefile.name.
Then nuke that file.
I think I have fixed it by going the wbdata folder in Appdata\Local\wbdata and deleting the cache file that was in it. seems to work now.

Please help!
I had the same problem in spark 1.2.0 but not in spark 1.0.2.
The reason was in my case that I had cygwin in the DOS classpath.
Spark uses the find command in the file 'spark-class2.cmd', which used then the cygwin find command instead of the DOS find command, which works somewhat different.
I removed cygwin from the DOS PATH, which solved the problem.

My Python interpreter is giving me an ugly error when I try to pull up a list of all the accessible modules (see below). I've googled "wx._core.PyNoAppError: The wx.App object must be created first!" and I haven't found a good explanation of how to fix it in this context. Can anyone help me out?

if you call help('modules') then, as defined in your site.py, pydoc.help() is called.
This results in a call to Helper.listmodules() which then calls the ModuleScanner() which is 'An interruptible scanner that searches module synopses' as per its docstring.
Unfortunately not all modules/packages are capable of being scanned, as that includes importing the module. You are however lucky that you just get an error. On my system (Linux, Python 2.7.3) this gives a segmentation fault
