Getting error with Django while requesting any url - django

I am running django on django's development server. It was working fine before but from yesterday i keep getting this error on the linux command line where server was running.
Exception happened during processing of request from ('57.xx.xx.123', 63721)
Traceback (most recent call last):

error: [Errno 32] Broken pipe
can anyone guide me that why it started happening now
This happen only 1 out of 10 times

"Broken pipe" means that there was still outgoing data on a file descriptor (a socket, in this case) when the destination closed down.
In this case, the most likely cause is the browser closing the connection before the Django development server has sent the entire response.

Occasionally I'll see a broken pipe after an exception, or when connecting to my Linux box form Windows when doing cross-browser/platform testing. I'm not exactly sure what causes these errors, but restarting Django's development server is all I know to do to fix it.

AWS SAM Accelerate fails to resolve dependencies when building application

I'm trying to use SAM Accelerate as recommended by AWS. However, the sam sync command is failing
PythonPipBuilder:ResolveDependencies - Could not satisfy the requirement: jsonpickle==2.1.0
The requirement for jsonpickle is included in the requirements.txt file, and it's installed locally.
foo#bar:~/sam-project$ pip freeze | grep jsonpickle
jsonpickle==2.1.0
The exact same error occurs when I use sam build, but I'm able to use the sam build -u to use a container and make the build work. Unfortunately that doesn't seem to be an option for sam sync.
I have found a few occurrences of a similar issue, but none of them address the root cause and this I am unsure of how to fix this.
Full output
foo#bar:~/sam-project$ sam sync --watch
The SAM CLI will use the AWS Lambda, Amazon API Gateway, and AWS StepFunctions APIs to upload your code without
performing a CloudFormation deployment. This will cause drift in your CloudFormation stack.
**The sync command should only be used against a development stack**.
Confirm that you are synchronizing a development stack.
Enter Y to proceed with the command, or enter N to cancel:

Unfortunately no one was able to assist here, so I opened an issue on GitHub.
Eventually the issue became clear and it's not actually an issue with SAM. The problem is that I use an AWS BuildArtifact feed, so any sam build or sam sync action will try and pull packages from that feed. However, the token for that feed expires after 12 hours.
The issue remains open and the SAM team are investigating the error that is displayed, and hopefully they will implement a solution that will surface the underlying error message, which would have made diagnosing this issue a whole lot easier.

"configparser.DuplicateOptionError" when running AWS CLI command

When executing the following command in the mac terminal I got an error: aws configure
I couldn't really find anything helpful online and I am newbie to mac and to aws. Can somebody please help me fix it?
same thing would happen with other commands like aws --version
commands like which awswould work normally

Based on the comments. The solution was to delete existing .aws/credentials and create new one using aws configure command.

I have Yocto on Edison and firmware version is 201606061707
Can anyone help me?
Thanks in advance!
--- Edit ---
I found the solution. freetype2 and libpng packages cannot be installed so I installed them manually and problem was solved!
I will suggest you to uninstall python and install Anaconda2 for python 2.7. It comes with all necessary module, including matplolib, numpy, pandas all.

Python SpeechRecognition error

I am exploring speech recognition and came across this python library called SpeechRecognition. I am running a linux mint system and have followed the troubleshooting steps on the webpage linked above. However, I get the following error:

Bottle micro framework suddenly crash

i have web app that i have developed using bottle micro framework.
However it crash a lot and all of them suddenly without any action ( without using the web app) . So i have reviewed the logs file and find the following errors (i have no idea what the causation of these errors):

OSError: [Errno 2] No such file or directory: '/tmp/bottle.gQmJc8.lock'
However the second error doesn't crash the application ( application would continue working ) but for the first one it's require manual work ( run the app again ).
i could schedule task using cron job to run the application when it's crash. but i'd like to know what's the problem in my app.
A few ideas come to mind:
Could there be another program on your machine (e.g., a cron job) that is deleting files from /tmp?
Are you using the latest version of Bottle? (From the line number in your stacktrace, it looks like you might not be.)
If nothing else works, try running without reloader=True (or use reloader=False). I looked at the Bottle code, and that change should at least work around the problem, even though we don't know the cause (yet).
Hope that helps.
