Spyder keeps crashing during load in all Anaconda environment

I was running python 2.7 in Anaconda2 in spyder 4 up until today with no problems. But now I keep getting the same error, when I make an environment and install python 2.7 and spyder in it:
Traceback (most recent call last):

This started happening after I reinstalled the package "pydicom" in the environment, and now nothing works. I have reinstalled anaconda2, used spyder --reset, and all other common suggestions.
Spyder 3.3.6 works in the base environment, but every time I make a new environment and install spyder in this, I get the same error. Any suggestions?

(Spyder maintainer here) To fix this problem, you need to install QtAwesome 0.7.3 in your environment. For that, please use the following command:
conda install qtawesome=0.7.3

Not able to launch Spyder version 4.1.1

I recently created a new environment with Anaconda Navigator and installed in it the Spyder IDE version 4.1.1. The problem is, whenever I try to launch it (via Anaconda Navigator), it raises me the following exception, and doesn´t launch at all:
Traceback (most recent call last):

But when I go to the root environment and try to launch from there Spyder version 4.0.1, it launchs with no issues.

I've installed the package:pywinauto successfully with "pip install pywinauto", but it always fail, why?

all,
I've installed the package:pywinauto successfully with "pip install pywinauto", but it always fails, why?
I did it in this way:
pip install pywinauto
and then under the windows cmd env, I run the python:
and then:
import pywinauto
I got the following errors:
....
>>> import pywinauto

It looks like you're using old OS Windows version like Windows XP. MS UI Automation is included into Windows Vista and later. But you may install .NET Framework 3.0+ to get UIAutomationCore.dll available even on Windows XP. If you don't need MS UI Automation technology at all, just run pip uninstall comtypes and pywinauto will work with Win32 API only.

If installing .NET Framework 3.0+ doesn't help (or if it's already installed) and you need to use Win XP, install Windows update KB971513. It solved the loading library issue for me.

I need upgrade the Winxp to Win7 or Win8, or Win10.

Can not run robotframework-ride properly

I have installed robotframework-ride on two PCs of mine. Everything works fine on one PC but could not have RIDE running on other PC.
I have the following installed on both PCs
- Python 2.7.8 on win32
- Robot framework 2.8.6
- wxPython 2.8.12.1
- robotframeowkr-ride-1.4.1b
When I tried to execute "python ride.py" on the second PC, I got a message:
Traceback (most recent call last):
File "C:\Python27\lib\site-packages\robotide__init__.py", line 74, in main

line 35, in find_installed_robot_libraries
rf_file, rf_version = output.strip().split(', ')
ValueError: too many values to unpack
Use --help to get usage information.
Something more interesting is, if I uninstall robot framework from the second PC, I could execute "python ride.py" but of course there is no point doing this.
Anyone can help me out here?

With kind assistance from janne, I have solved this problem. The cause is for the first PC I installed the correct "robotframework", but for the second PC I managed to install a wrong module, "robot" instead of "robotframework". That was why RIDE was not working.
I am sorry for making such a silly mistake. A big thank you to janne for his help.
should use: pip install robotframework
should NOT use: pip install robot

PIL Module with PyDev

I am new to Python and also Google App Engine, but I am stuck up with the installations of it and its compatibility. I am using mac os -x and eclipse helios and got the pyDev plugin installed but in spite of all this i am still getting errors. . .
Whenever I try to import PIL from the terminal it does not give me any errors meaning that it was installed successfully but when I use the same Import in the eclipse file. I getting the compilation error as:
"Unresolved Import"
Please help me with this
Somehow I tried to fix that, then it gives me the error saying that imaging : no matching architecture in universal wrapper
when I changed the architecture to 32 bit ti gives me this in Eclipse Log :

What do I do :( ?

PIL has some specific instructions for installation. Have you seen them?
Installing PIL on GAE
Download the PIL .dmg file. For example, you can download the PIL 1.1.6 .dmg file from http://pythonmac.org/packages/py25-fat/index.html.
Double-click on the installer to start the installation process.
Choose the correct directory. Finish the installation.
This is just for use in your local development environment. When you upload it'll use a GAE supplied version of PIL which means you also have to update your app.yaml file like so:
libraries:
- name: PIL
version: "1.1.7"
as detailed here.
IIRC You will want to install it "inside" your application directory itself so it can be accessed by your application locally. Not sure about that on the MAC however.

I just installed Pillow (using: sudo pip install Pillow) to get PIL in Python 2.7.6 on OS X 10.8.5 Mountain Lion.
I had the same issue in PyDev with Eclipse Kepler. To fix:
Go to:
Eclipse -> Preferences -> PyDev -> Interpreter - Python -> Libraries and click on "New Folder."
Then navigate to:
/Library/Python/2.7/site-packages
and click Open, and then Apply, then OK.
Then I quit Eclipse and restarted -- problem fixed. :)
