I am tying to use Flask-MongoEngine which is working fine, but I am trying to get the debug toolbar to work and when I follow the documentation I get a traceback shown below. I am able to run the normal flask debug toolbar fine but since I am using MongoDB as the database I am trying to use the flask debug toolbar with MongoDB. I know that the following line is the cause of this traceback `
app.config['DEBUG_TB_PANELS'] = ['flask_mongoengine.panels.MongoDebugPanel']
example code
from flask import Flask
from flask_debugtoolbar import DebugToolbarExtension
app = Flask(__name__)
app.config['DEBUG_TB_PANELS'] = ['flask_mongoengine.panels.MongoDebugPanel']
db = MongoEngine(app)
toolbar = DebugToolbarExtension(app)
line that causes traceback
app.config['DEBUG_TB_PANELS'] = ['flask_mongoengine.panels.MongoDebugPanel']
#traceback

'_unpack_response': pymongo.helpers._unpack_response,
AttributeError: module 'pymongo.helpers' has no attribute '_unpack_response'
The _unpack_respone method seems to be gone or rewritten since pymongo 3.6.0.
A workaround is to install pymongo<3.6.0
I'm new to django and using the anaconda cloud environment. Its been working well for 3 months plus but as of 7-24-2018 it is just stop to launch the navigator or open through cmd. I can't manage environments or install packages. Using the anaconda prompt also gives me the same error upon launching. It started when I wanted to install django-Oscar, but not having its dependencies I was forced to install the packages manually which in turn needed cytoolz that needs Microsoft Visual C++ build tools which I got to install as well but the error persists. Please help me!

I've just found out that I cant even use any conda commands except the : >conda --version< command only.
Please help me resolve this issue without uninstalling then reinstalling anaconda completely
Sorry to waste your time, I solved it by reinstalling anaconda completely and every project started working again....thanks to those who read it, the effort is appreciated.
It usually happen when you directly download and insall anaconda normally form its website.
Updating anaconda solved this issue for me in Manjaro and will surely work on Windows as well.
use conda update anaconda-navigator command to Update Anaconda.
If it doesn't starts, restart your pc and try to open it again.
I am trying to get pyttsx3 up and running on my computer. I did pip install pyttsx3 and pip install pypiwin32 I can see both of them in my python directory.
I type this code in to test it:
import pyttsx3
engine = pyttsx3.init()
engine.say("I will speak this text")
engine.runAndWait()
This is what comes out:

I tried the same thing on another computer that already had both installed, and got the same output. Any idea what is going on with the win32com? I have no experience with it and am pretty lost. Thanks.
Ok, so I found the answer looking at other problems that were related to the win32com module. Basically what you need to do is navigate to your python scripts folder (in my case: C:\Users\Danny\AppData\Local\Programs\Python\Python36\Scripts) and run pywin32_postinstall. Upon running that script, it works perfectly!
Cheers!
I am struggling to setup pymunk on my Ubuntu 16.04. I am using virtualenv, I have Python 3.5.2, pymunk 5.3.0 and cffi 1.11.0 installed.
I tried a very simple code first; basically, I created an empty Space and called step on it and everything worked smoothly. However, when I try to visualize it and create DrawOptions instance, I get strange errors, which I can't decipher. Also, I tried matplotlib_util and pygame_util, but both failed to create DrawOptions.
This is the code snippet I used:
import pymunk
import pyglet
import pymunk.pyglet_util
s = pymunk.Space()
options = pymunk.pyglet_util.DrawOptions()
s.debug_draw(options)
# s.step(0.02)
This is the output I get:

What do you think is causing that? Is that the python version I use, or maybe cffi compilation is faulty?
This error happens because there was a new version of pycparser (which is used by cffi) released, and that version breaks pymunk 5.3.0 and earlier versions. Yesterday I made a new release of Pymunk, 5.3.1 with a workaround for the problem. If you try to update your Pymunk version to 5.3.1 it should work.
Hi I am unable to use the "print_control_identifiers()" for my desktop application.
I am using a) Python 3.5.3 (32 bit since my application I am automating is 32 bit)
b) Pywinauto 0.6.2.
My simple code is as follows:
`from pywinauto import Application
app = Application(backend="uia")
app = Application().start(r"C:\Program Files (x86)\Trane\TRACE 3D Plus\TRACE™ 3D Plus.exe")
app['TRACE™ 3D Plus'].print_control_identifiers()`
When I run the above command, I got the following in command prompt:
Traceback (most recent call last):

Can anyone tell me what the problem is and what I could do to resolve it ?
Thanks in advance !
Replace these commands
app = Application(backend="uia")
app = Application().start(r"C:\Program Files (x86)\Trane\TRACE 3D Plus\TRACE™ 3D Plus.exe")
with this one:
app = Application(backend="uia").start(r'"C:\Program Files (x86)\Trane\TRACE 3D Plus\TRACE™ 3D Plus.exe"')
Because you re-create app object with default backend="win32" if not using any argument. If it's hard to understand, I'd recommend to get a Python course first. Basic Python programming skills is necessary here to understand what's going on.
