I'm attempting to run a Django app that uses Celery and I'm receiving the following error:

from billiard.exceptions import ( # noqa
ImportError: No module named exceptions
billiard is installed and the exceptions module does exist, and I'm able to import billiard.exceptions via Python's interactive prompt without issues. It seems that celery is failing to import billiard. Any ideas?

I'm following along a course - Django development to deployment.
After pulling it to Digital Ocean everything else ran smoothly. Until
I tried running python manage.py help

and I get this error.

ImportError: No module named 'secrets'
I'm a newbie and have been stuck on this for a while. I just want to know what could possibly cause this.
The secrets module was added to Python in version 3.6. Your host is using Python 3.5, hence the secrets module is unavailable. You need a host with Python 3.6+, or a version of Django that doesn't depend on the secrets module
Had the same issue, solved it by specifying the python version I have installed. i.e
$ python3
>>> import secrets
>>> secrets.token_hex(16)

When I debug through werkzeug/http.py file I came across the below code and in python command line from urllib2 import parse_http_list is working fine but in code, it is going to exception block.
from urllib2 import parse_http_list as _parse_list_header
except ImportError: # pragma: no cover
from urllib.request import parse_http_list as _parse_list_header
The module urllib.request is for Python 3. You are using python 2.
From Werkzeug 2.0.0 changelogs:
Drop support for Python 2 and 3.5
Either downgrade Werkzeug or upgrade to latest python 3 release.

I run the script from the first directory it ran from $MDS_SRC/ and it runs fine.
I can copy the entire script to my local directory , and it errors out.
I have created a simple, Google App Engine application that works with the Google docs api.
it requires the app_engine module from google.auth (from google.auth import app_engine), which I have installed in a /lib folder and added vendor.add('lib') to appengine_config.py
However, when I deploy from google cloud SDK to the app engine standard environment, I am getting the following error:
'importError: cannot import name base'
I am also getting the error:
'ImportError: No module named pyasn1.codec.der'
For both issues I have doubled checked that the base and pyasn1.codec.der modules are actually present in the lib folder. In both cases they are.
Does anyone have any idea what the problem might be?

Make sure that the Python modules and objects are properly installed.
Note that in App Engine Python runtime environment, Python client libraries must be vendored into your application as they are not installed in it.
More references are discussed here[1] specific for Google Docs API.
Also make sure that you have obtained credentials with [2]:
from google.auth import app_engine
credentials = app_engine.Credentials()
Since the error is coming from google.auth.crypt module you may also check on this page[3] for more info.

I had the same problem, and I go to "google" directory and delete the "auth" manually.
After I run
pip install google-auth
and it's start working.
I'm trying to run my program as an administrator from the command line. Seems quite easy but I'm struggling.
I started with this, which works fine launched from the Python IDLE:
import dropbox, pymysql, shlex, shutil, subprocess
import logging
import sshtunnel
from sshtunnel import SSHTunnelForwarder
# Main program starts here
print("Hello World!")
but that gave an error as follows:
pi#jsmd:~ $ sudo python /home/pi/Documents/iot_pm2/iot.py
Traceback (most recent call last):
File "/home/pi/Documents/iot_pm2/iot.py", line 3, in <module>
import dropbox, pymysql, shlex, shutil, subprocess
ImportError: No module named pymysql
After some Googling I added two lines at the start:
import sys
sys.path.append("/usr/local/lib/python3.4/dist-packages/")
This also works fine from the Python IDLE but gives a long error trace when run from the command line... and I'm not good enough at understanding how to read the trace and hence what I can do to fix it. (Plus I don't understand why it works from the IDLE as a non-admin but not from the command line as an admin.) Can anyone help?

Thanks.
is the default of python is 3 ? If not try to execute like this: sudo
python3 ... – #Koffee
Thanks to #Koffee we have an answer and this thread can be marked as solved and closed.
