I have neo4j-2.1.3 installed and server running on my Linux system . I created model "publisher" in my app . And then in manage.py shell , whenever I save a node with
from BooksGraph.models import Publisher
p=Publisher.objects.create(name='Sunny',address='b-1/196')
a long error pops up with:

This sounds like a network setup problem. Can you check what URL the library is trying to connect to and that that one really goes to your local Neo4j Server?

I cannot install any pip package in my pc it returns that error .I am using v2ray and proxyfire.I don't think these software make trouble with pip command because I use it without any error before formatting my PC.
I already installed Python and added into env var : Python 3.10.1
Appreciate Your support .
I also met the same problem, the reason is Clash Proxy or System Proxy trigger the problem.
so, you need to close Clash or switch off the system Proxy.
What if, in order to boost the downloading speed,you can install TAP Device and open the Service Mode in Clash instead of using System Proxy mode.
I download anaconda as the Internet said, and use command 'conda create -n python python=3.6' and it shows "Collecting package metadata (current_repodata.json):failed" and the error report says:

This is not how pyinstaller works. Rather than importing pyinstaller into your program, you need to run pyinstaller pointing at your program.
From the docs:
Install PyInstaller from PyPI:
pip install pyinstaller
Go to your program’s directory and run:
pyinstaller yourprogram.py
you can use auto-py-to-exe
pip install auto-py-to-exe
to run it
$ auto-py-to-exe
I am a newbie with Python, just install newest 3.9.5 in Windows.
I use pip to install requests module and fail with error "check_hostname requires server_hostname"
All solutions I found is to install old urllib3 module like "pip install urllib3==1.25.11".
But again, I fail with error "check_hostname requires server_hostname" as below. What can I do now?

Thanks to simpleApp's hint in comment!
I am in China and run a proxy program actually. I can successfully install module requests after I close my proxy and try again!!
I am attempting to upgrade my tensorflow via conda but am having some issues. I am following the Anaconda installation procedure here.
I am getting an error when I execute the conda create -n tensorflow command.
Here is the error:

I'm done some googling and haven't been able to find a useful response. Any help would be much appreciated.
Your conda is using python 2.7, you may have to upgrade it to python 3.x
I say this because in the anaconda installation guide you linked, it shows a call to print with parentheses, which is python 3 syntax
