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.

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

Upgraded MetPy to 1.1 and my ability to produce satellite images from a THREDDS server is no longer working. I isolated the part that is causing me issues.
Example:
#!/usr/bin/python3
import metpy
from siphon.catalog import TDSCatalog
cat_e = TDSCatalog('https://thredds.ucar.edu/thredds/catalog/satellite/goes/east/products/CloudAndMoistureImagery/FullDisk/Channel09/current/catalog.xml')
nc_e = cat_e.datasets[0].remote_access(use_xarray=True)
data_e = nc_e.metpy.parse_cf('Sectorized_CMI')
yields the following output/error

I appreciate any thoughts on how to get around this.
Can you double check that your Python installation with MetPy is correct? I was able to run your code fine on my local install of MetPy 1.1.0 with Python 3.9. Also, your traceback shows Python 3.6 being used; MetPy 1.1.0 only supports Python >=3.7. You should not have been able to install MetPy 1.1.0 with that version of Python.
You can confirm the version of MetPy being used by adding the following to your script:
print(metpy.__version__)
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 Not really sure it was out of date.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 am using a python package from Gray Arrow's Dejavu. I have installed all the required dependencies and other packages necessary to run my code. When running the following code:
import warnings
import json
warnings.filterwarnings("ignore")
from dejavu import Dejavu
from dejavu.recognize import FileRecognizer
with open('dejavu.cnf') as f:
config = json.load(f)
djv = Dejavu(config)
djv.fingerprint_file('mp3/Sean-Fournier--Falling-For-You.mp3')
song = djv.recognize(FileRecognizer, 'mp3/Sean-Fournier--Falling-For-
You.mp3')
print("from file recognized: {}\n".format(song))
I receive the following errors:

I have done complete re-installations of python 3.7 and all of the packages and dependencies to attempt correction of this problem.
I do not understand what file cannot be found and have done research in hopes to find an answer to this issue. I truly appreciate any help and knowledge that can be shared with me on this topic.
Try and place "Sean-Fournier--Falling-For-You.mp3" file in the exact directory you have your script, I don't think the folder reference to the mp3 folder is being handled correctly :)
djv.fingerprint_file('mp3/Sean-Fournier--Falling-For-You.mp3')
song = djv.recognize(FileRecognizer, 'mp3/Sean-Fournier--Falling-For-
You.mp3')
I use Spyder to run my python codes in my Mac OS x.
It happens that spyder just crashed, and since them it doesn't open anymore.
When I try to open it directly from ~/anaconda/bin, the following error msg appears:

I tried to do what the error msg suggest, and use the option --reset, but the same error still exist after that.
Anyone has any idea on how to solve this issue?
It is known that the MacPorts version of Spyder is raising this error:
ValueError: unknown locale: UTF-8
which doesn’t let it start correctly.
To fix it you will have to set these environment variables in your .profile (or .bashrc) manually:
export LANG=en_US.UTF-8
export LC_ALL=en_US.UTF-8
I would like to save a python plot. With MacOS everything runs smoothly but it fails under Windows7.
The python-command looks like this:

The error messge is this one:

This is the Python I'm using:

Can anybody explain the cause of the problem?
I think you have to add r before your directory to convert your string into raw string. See this post
Unknown python expression filename=r'/path/to/file'
