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):

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.
Regards.

I have a Python Code to conduct an experiment. To ensure that the Code is working smoothly I wanted to run a trial round via 'otree devserver', but I always get an AttributeError message and I am stuck here. Can anyone help me out?
I have downloaded the Code from GitHub and downloaded all required packages. I am using macOS, otree-5.10.2 and django-4.1.7. Here is my full traceback / error message:

I have installed librosa correctly with pip3 on ubuntu subsystem on windows, but when I try to execute a simple program like this one:
import librosa
data, sr = librosa.load('sound.mp3')
print(data.shape)
It is what happens:

What am I doing wrong?
According to the manual you'll probably also need to install ffmpeg, to allow for librosa to decode various formats.
Since you're working in the Ubuntu subsystem, simply
apt install ffmpeg
should do the trick.
I recently installed yahoo_fin and I tired the following example:
get_calls('NFLX' ')
It worked. I then tired the following:
get_calls('NFLX', '11/8/2019')
It failed. Here is what I got:
get_calls('NFLX', '11/8/2019')

I am using version 3.6.3 of Python and I am also using Spyder.
Am I doing something wrong? Do you think I have found a bug?
I updated my version of yahoo_fin. Not really sure it was out of date. I now get the following error messages when I run the command: get_calls("nflx", "1/31/20")
Traceback (most recent call last):

It should work the way you have it.
from yahoo_fin.options import get_calls
get_calls("nflx", "1/31/20")
Are you using the most recent version of yahoo_fin? It should be (as of this writing) version 0.8.4. Another possible issue is that there could have been a problem with Yahoo Finance's page for that option chain at that particular time.
I'm planning to use the Language-check module for python 3 in my poem making code. I was just testing it with
import language_tool
lang_tool = language_tool.LanguageTool("en-US")
text = "A sentence with a error in the Hitchhiker’s Guide tot he Galaxy"
matches = lang_tool.check(text)
print(len(matches))
but it gave me this error.

I've looked at some similar questions and I know I probably need to put something in 'Path' but I don't know what specifically to enter. Thanks for your help!
Also I'm on doing this on repl.it, not IDLE.
Note: I'm adding this as an actual answer because the question was resolved in the comments.
Your question says:
Also I'm on doing this on repl.it, not IDLE.
That means that you need to install this module and all its prerequisites into your repl.it environment, not into your local machine.
On the BitBucket link you provided, under "Prerequisites", the page says:
LanguageTool requires Java 6 or later.
So you will need to ensure Java is installed into your repl.it environment somehow. I don't know whether that is possible or not. Alternatively, you can simply install this package and all its prerequisites locally instead.
I have this problem with Spyder(in Windows 10). When I try to do anything on my spyder console (even something as simple as 1+1), I get the following error message in the internal console tab:

The problem gets resolved when you install Spyder 3 like Carlos mentioned
This error was fixed in Spyder 3.0.2. Please update to that version.
However, it actually does not impacts my codes or run times. The only drawback is that you cannot test your codes out on the machines which shows this error.
