I can't pin it down to any single source. It seems to happen randomly, afaik. It causes the page I'm testing to load up really long, and the page just loads fine.
Using Django 1.3 Beta 1
UPDATE: I'm using Opera/Firefox for testing now, and the problem hasn't come up since. I'm afraid to try again in Chrome.
I got the same thing and asked on django-users google group. Nobody had any idea what's wrong.
It seems only I get this when I refresh the page from browser and not when I click on links inside the page.
Also just as a heads up: I tried on Python 2.6 and 2.7 both stock version (form python.org website) and ActiveState one. Same thing happens randomly.
LE: I'm getting this on the stable version of Django.

I'm deploying my first django application following Digitalocean's tutorial on deploying with postgresql database and it won't let me access my webpage in a browser. In the browser it says, "This site can't be reached". Port 8000 is allowed through the firewall as well. Any ideas on what to do?

I updated my Django project to version 2.2.2 and now when I call to ipdb for debugging, the server tell me that error. If I go back to Django 2.2.1, the error disappears.

Can somebody know what's the problem there? I'm using django runserver in local machine, with celery and postgresql database.
Thanks!! :)
Try using the --reload flag to run runserver.
./manage.py runserver --noreload
It stops the server reloading on code changes but I think avoids the issue you're having.
I am using pyspark with Spark 2.2 and Python 2.7.11 and I am trying to extract rules from the decision trees of a random forest classifier using the .toDebugString Method.
I had success with it but since the update from 2.1 to 2.2, Spark crashes after I use this command and I get this error:

If I run the command again after this error I get:
Py4JError: An error occurred while calling o1129.toString
My code is fairly straightforward and this confuses me very much.
#Get random forest from pipeline
rfModel = model.stages[1]
rfModel.toDebugString
I know rfModel is a randomForestClassifier object. Any ideas why I get this error?
The solution to my problem was the python version. By using python3+ with spark 2.2 i managed to work .toDebugString method without a problem. I will update with full error log for anyone seeing this in the future.
I just had my computer re-imaged and have Python 2.7.9 (64-bit) installed on my machine. Using PIP I have beatbox 32.1 installed.
When I make the call to connect to Salesforce:
sf_client.login(sf_username, sf_password)
logging.info('Connected successfully')
I receive an error message. I have tried just the normal login credentials which has always worked and have attempted to connect with my token in the password too.
Has anyone run into this error with Python Beatbox and do you know what debugging options I could try to get to the bottom of this?

ssl.SSLError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:581)
After searching and googling profusely about TLS connections, etc, I noticed this weekend that my cmd.exe window (which I run the PIP commands from) was launching under C:\Windows\System32> and all of my vms were launching within my personal user directory.
So I searched for my roaming cmd.exe and when I opened that, it was to my personal user directory.
After doing an uninstall and install of beatbox using PIP in the new cmd.exe, all of my Salesforce calls via Beatbox work like they used to.
Now I can't fully explain why this is the case, but something tells me that the certs for this admin location are probably mismatched to my personal certificates. I'm up and running again.
Out of the blue today I started having this problem.. in trying to run the Python Shell from my .py file. The shell window opens with a blinking cursor. If i type anything and hit enter the following error hits. Python IDLE doesn't work at all and I only get this error.

Python (command line) works fine, but the IDLE does not. I've tried rebooting windows and system restore with no luck. I've been googling for answers with little success. My firewall has always been disabled. Trying to start IDLE from command line returns the following error.

Windows -32bit OS. thanks in advance for your help.
This is really weird. But a great question you posted! Nice to read.
Here could be a solution: https://stackoverflow.com/a/3277996/1320237
Why would it be impossible to import the Calltips module from the standart library? Maybe you have a Python 3 idle open? Then they interfere?
Well my impatience got the best of me. I copied my site-packages file to the desktop and uninstalled/reinstalled Python. Pasted the site-packages back into my Python directory and all is right with the world again.
