I'm trying to connect to wiimote via Python on mac osx 10.7.2.
For that I'm trying to use lightblue. When running: import lightblue Python gives me this error.
>>> import lightblue
Traceback (most recent call last):

ValueError: cftype for 'IOBluetoothDeviceInquiryRef' must include gettypeid_func, tollfree or both
I found one with a similar problem here: http://python.6.n6.nabble.com/Python-bridgesupport-issue-on-Lion-td2161049.html#a32196961 but the answer doesn't help me much, since it seems to me that it is already using lightblue's files. Any suggestions?
Seems like a bug with Apple's gen_bridge_metadata script. You can make the error go away by editing the generated file by hand.
Open up /System/Library/Frameworks/IOBluetooth.framework/Versions/Current/Resources/BridgeSupport/IOBluetooth.bridgesupport and delete the lines that start with <cftype.

I am trying to learn Python and following along some modules. I am using Anaconda Powershell Prompt and using Python 3.7 from there. I am trying to follow along via the code below.
Everything works until I get to the line
from wrf import getvar
When I do that line I receive this
>>> from wrf import getvar
Traceback (most recent call last):

TypeError: <class 'numpy.typing._dtype_like._SupportsDType'> is not a generic class
Looks like the last few lines return an error but as a beginner I have zero clue what this means.
This looks like a similar error to <class 'numpy.typing._dtype_like._SupportsDType'> is not a generic class when importing the plotly.express library - an incompatibility between wrf-python and numpy.
Try upgrading those libraries to the latest versions.
Today I've run into problems trying to use the python-bitcoinlib in a small python program. It worked perfectly a few days ago but today the library seems to be broken (see console output below).
I'm in a Mac with OS X 11.0.1 (yes, I upgraded today, but I would be surprised if that's the cause of the problem).
I've tried several times installing and uninstalling the library and even python, but nothing seems to happen.
Thanks in advance.

My solution is not using RawProxy.
Impor this instead:
from bitcoinrpc.authproxy import AuthServiceProxy
And connect to bitcoin core with this sentence or equivalent:
p = AuthServiceProxy("http://%s:%s#127.0.0.1:8332"%(rpcuser, rpcpassword))
I have a small python (2.7) script that works with several threads. One of the threads will read a global list and post an https post request for each one of the entries of this list.
For doing that I saw that the best way is to use python requests module. I have installed it with pip (no problem with that, it is placed in ...Python/2.7/site-packages/requests/...), but, when I import this module in my script, I get an error.
I have created another script with just one line (import requests) to reproduce the error, and I get this:

Am I doing something wrong? Didn't I installed the module in the proper way?
it seems that you're having two modules with the same name array.py
rename your local array.py module to something more unique to resolve this.
take a look at this answer for more info on how to handle this issue and here to learn more on how python import system works.
I've tried to make my own server to new sync service in FireFox.
I used the following tutorial: https://docs.services.mozilla.com/howtos/run-sync-1.5.html .
When I wanted to check it by using make test I got the following error:

What's happened?
configparser.ExtendedInterpolation does not exist in Python 2.
You need to use Python 3.
I added the following plugin to sublime text 2 which is meant to open the ipython qt console:
import sublime, sublime_plugin
from subprocess import call
# import os
class ipythonQtCommand(sublime_plugin.TextCommand):
def run(self, edit):
call(["start","ipython", "qtconsole", "--pylab", "--ConsoleWidget.font_size=9", "--ConsoleWidget.font_family='Consolas'"],shell=True)
Initially it worked just fine, i.e. the plugin opened an ipython shell. I then added a menu item and a key binding. At some point something must have gone wrong since now I get this error when I run the plugin:

ImportError: Module use of python26.dll conflicts with this version of Python.
I tested the script by running it line by line in the st2 shell itself and it is the last line call([...]) that causes the error. I find this a little strange since the command works ok when calling it from somewhere else, e.g. ipython itself.
There seems to be a conflict with the st2 native python. In any case I managed to get os.system(...) to work when changing the working directory using os.chdir().
