Issues Opening Spyder via Anaconda

I was forced into some software updates on my laptop (ThinkPad) and after the update when I tried to open Spyder (via Anaconda) and it won't open. I don't have any experience in errors like this or fixing this stuff (and I am aware this may be something that is super simple). Please help. This is the application launch error I am getting:

Thanks,

Did you try to run spyder on the terminal?
It should be prebuild in Anaconda.

Your Spyder config file should contain but is missing 'custom-1/background' in section: 'appearance'. If you have no experience, the easiest thing for you to do is uninstall and install Spyder (via Anaconda). Your other option is to find the config file called in line 513 of C:\Users\cyrra\anaconda3\lib\site-packages\spyder\config\user.py". Then open the config file (if it exists) and correct it. If the file is not found, search for that config file and place it in the expected location.

After starting spyder: ImportError: cannot import name 'quick_guide'

When I start spyder the internal console pops up and gives the following "traceback":
>>> WARNING:traitlets:kernel died: 6.001837253570557
Traceback (most recent call last):
File "C:\...\lib\site-packages\traitlets\traitlets.py", line 528, in get
value = obj._trait_values[self.name]
KeyError: 'banner'
During handling of the above exception, another exception occurred:

File "C:\...\lib\site-packages\spyder\widgets\ipythonconsole\shell.py", line 91, in long_banner
from IPython.core.usage import quick_guide
ImportError: cannot import name 'quick_guide'
The IPython console works without problems, it is just missing the "introduction text" (python version, help-commands).
Can I just ignore this exception or is there a way to fix this manually?

(Spyder developer here) This was fixed in Spyder 3.1.4 (just released). Please update to fix it.

To fix the exception manually one needs to change the last mentioned file in the traceback. In this case this one:
File "C:\...\lib\site-packages\spyder\widgets\ipythonconsole\shell.py", line 91, in long_banner
from IPython.core.usage import quick_guide
ImportError: cannot import name 'quick_guide'
and change quick_guide to quick_reference as quick_guide. One may need to restart Spyder but then the Exception disappeared.

I solved:
Only use conda install spyder=3.1.4 in your conda env.

What does this capistrano error mean when doing an AWS file fetch via cap tasks?

In my deploy/development.rb, I have the following line:-
set :env_path, 's3api get-object --bucket <bucket_name> --key <file_name> <file_name>'
In my cap file, I have the following task defined:
task :download_configs do
on roles(:all) do
within release_path do
execute :aws, "#{fetch(:env_path)}"
end
end
# on roles(:db) do
# within release_path do
# execute :aws, "#{fetch(:env_path)}"
# end
# end
end
But on cap deploy,I am seeing the following errors:-
cap aborted!

Please help me identify what is going wrong here!

Shot in the dark (I'm not a Python dev), but you might be able add the following to deploy.rb:
set :default_env, {
'LANG' => 'en_US.UTF-8'
}
Derived mostly from https://github.com/matplotlib/matplotlib/issues/5420#issuecomment-154454607
I would check to see if you can run the command manually on the server. If you cannot, then figure out how to without Capistrano. If you can, perhaps see if there is some configuration in .bashrc or .bash_profile that can be added to the Capistrano config.

matplotlib does not import in python3 [duplicate]

This question already has answers here:
Pelican 3.3 pelican-quickstart error "ValueError: unknown locale: UTF-8"

I have OSX El capitan, and get the following error when trying to import matplotlib in python 3:

I tried to delete the matplotlib folder, and reinstall it with pip install matplotlib, which it recreates it, but it ends up giving the same error.
I already spend half the weekend trying to find an answer but no luck - maybe somebody can help.
Best

Found a solution here. Basically what you have to do is add two lines to your ~/.bash_profile (and re-open terminal window):
export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8

Cannot Import GTK in Ubuntu Python 2.7

I'm trying to import GTK in Ubuntu Python 2.7, and I get the following error. PyGTK imports just fine. When I import gtk, I get the following error:

lineno, file=file, line=line))
TypeError: idle_formatwarning() got an unexpected keyword argument 'file'
How do I fix this?

This is a bug in idle. Looking at the last line of that error message:
File "/usr/lib/python2.7/idlelib/PyShell.py", line 64, in idle_showwarning
lineno, file=file, line=line))
TypeError: idle_formatwarning() got an unexpected keyword argument 'file'
This is saying that the warning.idle_showwarning method does not have an argument "file".
Sure enough looking at /usr/lib/python2.7/warnings.py
def formatwarning(message, category, filename, lineno, line=None)
There is no such argument.
This apparently has been resolved in source control but I do not think it has made it into a release yet. I would just hack the /usr/lib/python2.7/idlelib/PyShell.py file and remove the offending argument from line 64.
Then try it again...

Try it outside of IDLE. The error here is in IDLE, not your code.
Create a new script that contains import gtk and save it anywhere.
From the command line, in the directory where your script is located, run python whatever_your_scripts_name_is.py.
See if you get an error. You may not be able to import gtk in IDLE.
Edit: There is apparently a problem with GTK and IDLE in some situations on Ubuntu.
Try a different Python shell; I'd recommend IPython which you can install with Synaptic or sudo apt-get install ipython.
