This might seem like an already asked question but I have searched for an answer for a week now and got nothing.
The problem is I have developed an API using Django which is hosted on a server. Now when I run the following command to initiate the server :
python manage.py runserver 0.0.0.0:9000
The server starts as usual. Its only when I send request to the server via "Postman" that I see the following error:
FileNotFoundError: [Errno 2] No such file or directory: 'manage.py'
The strange thing is there is no error in running the server but only when I send a request to it. Also I have many more Django APIs running on the same server with same python version(Python 3.4.3) and same virtual environment (but different port) that are running just fine.
Full error traceback :

Things I have tried:
I have tried changing the !# as suggested on various posts.
I have tried using dos2unix to convert the file to unix format(server on which my API is hosted is linux based).
I even have tried to create a new Django project.
And yes I'm running manage.py from the correct directory.
I have also tried making manage.py executable by :
chmod +x manage.py
Nothing worked for me so far. Am I missing something?
We have established pipelines scripts that work very well. Lately, we decided to deploy to elastic beanstalk automatically, with the use of bitbucket pipelines and following the tutorial which uses the command eb deploy to deploy. Apparently, this command fails on pipelines. The config files seem legit because it runs locally. It also runs from inside a container of the same image that we have specified in the pipelines file and also by using docker exec from the local to run the command inside a container of the same image. The following are the pipelines file and the error we get using eb deploy --verbose command. I am obviously missing something here. Any help or direction would be appreciated. Thanking you in advance.

Try python3 version of eb instead of python2.7. Might have more success.
I work at a large corporate organization where we have a Hadoop cluster. I got the admin to install virtualenv on all the Hadoop worker nodes so that I can submit mrjobs with standard Python dependencies that may not exist on the worker nodes. As per the documentation here, this is how my mrjob.conf file looks like:
runners:
hadoop:
setup:
- virtualenv venv
- . venv/bin/activate
- pip install nltk
I have a simple job that uses nltk package. I can verify that this setup script runs on the worker nodes (I can put simple commands like write some data to a file in /tmp and it works). However, I get the following error:
New python executable in venv/bin/python

What may be causing this error?
Thanks for this idea for deploying packages to the cluster.
As for your problem I think it looks like it doesn't have permission to write to the directory.
I am trying to run a python script using MRJob on a cluster in which I don't have admin permissions and I got the error pasted below. What I think is happening is that the job is trying to write the intermediate files to the default /tmp.... dir and since this is a protected directory to which I don't have permission to write, the job receives an error and exits. I would like to know how I can change this tmp output directory location to someplace in my local filesystem example:
/home/myusername/some_path_in_my_local_filesystem_on_the_cluster , basically I would like to know what additional parameters I would have to pass to change the intermediate output location from /tmp/... to some place local where I have write permission.
I invoke my script as:
python myscript.py input.txt -r hadoop > output.txt
The error:
no configs found; falling back on auto-configuration

Are you running mrjob as a "local" job, or trying to run it on your Hadoop cluster?
If you are actually trying to use it on Hadoop, you can control the "scratch" HDFS location (where mrjob will store intermediate files) using the --base-tmp-dir flag:
python mr.py -r hadoop -o hdfs:///user/you/output_dir --base-tmp-dir hdfs:///user/you/tmp hdfs:///user/you/data.txt

Any ideas?
Check the shared memory parameter, kern.sysv.shmseg on your linux system and set it right by increasing it.
To view the shared memory parameters, use:
sysctl -A | grep shm
To update that parameters, edit file:
sudo nano /etc/sysctl.conf
Refer to this SO answer for more information.
