i am using geany,and python3 (IDEL) on raspberry pi3
Can any body help me how i can fix this error ?
For others who faces Similar error like
ModuleNotFoundError: No module named 'multiprocessing';
would also occur if you name your python file as multiprocessing.(as it makes ambiguity between your program name and actual module name)
Just rename your file and it will work (if you have dependency installed).
Seems like you are installing multiprocessing in the python 2 version. Could you use pip3 to install the package?
pip3 install multiprocessing
Also use the following command to check which pip you are using
$ ls -l `which pip`
$ ls -l `which pip3`
And to see if the package got correctly installed or not use
$ pip show pip
$ pip3 show pip
Update:
multiprocessing is built-in after python2.6
OP did a typo. It should be
import multiprocessing in place of import mutiprocessing

Python noob here. I've been trying to install pygame and pandas for a few hours now. Even with Conda I did not succeed. I have Python 3.8.5 installed.
I eventually tried through the terminal with these commands:
python -m pip install pygame==2.0.0.dev6
and
python -m pip install pandas
(this was a total guess by the way, but apparently it did something)
Results were succesfull:
Requirement already satisfied: pygame==2.0.0.dev6 in /opt/miniconda3/lib/python3.8/site-packages (2.0.0.dev6)
and
Successfully installed numpy-1.19.2 pandas-1.1.2 python-dateutil-2.8.1 pytz-2020.1
But, when I try to import either modules, I still get errors. Any ideas?
import pygame
Traceback (most recent call last):
File "<pyshell#1>", line 1, in <module>
import pygame
ModuleNotFoundError: No module named 'pygame'
import pandas
Traceback (most recent call last):
File "<pyshell#2>", line 1, in <module>
import pandas
ModuleNotFoundError: No module named 'pandas'
Do I need to move the modules to the script folder or something? Or what do I even move? Thanks!
Ok.. Got it thanks to #matt.. after succesfully installing pygame, find the environment in which pygame is installed by entering 'which python'.
In my case it returned:
/opt/miniconda3/bin/python
Now I needed to make sure the VS console was pointing at the same environment, by checking which python interpreter it was using and selecting the correct one. More info:

I'm new to python. I'd like to use requests module. but when i type in $, the system shows me "invalid syntax" Is the problem lays in the $?
$ pip install requests
Returns:
SyntaxError: invalid syntax
import requests
Traceback (most recent call last):
File "<pyshell#18>", line 1, in <module>
import requests
ModuleNotFoundError: No module named 'requests'
You need to run
pip install requests
in the command line.
For Windows, the command line would be called cmd or PowerShell.
For MacOS, it would be called Terminal.
and for Linux, it would be called Shell or Terminal. (in which case you might need to call pip3 instead).
From there, you can do
import requests
in any Python file.
I installed dash with pip3, all worked well and showed in the "pip3 list" command.
Nevertheless,when I import it in my script and run my script, I get this error:
File "app.py", line 3, in <module>
import dash
ModuleNotFoundError: No module named 'dash'
Did that happen to anyone ?
(fyi: running it on mint)
After installing cassandra driver by running the command:
sudo pip3 install cassandra-driver, I am getting the error ModuleNotFoundError: No module named 'cassandra' when I try to import the module by running the line cassandra.
I then tried to see what all modules are installed in pip3 by running the command pip3 freeze:
astroid==2.1.0
cassandra-driver==3.16.0
isort==4.3.4
lazy-object-proxy==1.3.1
mccabe==0.6.1
pylint==2.2.2
six==1.12.0
wrapt==1.10.11
Seeing no cassandra, I tried to import the visible module: cassandra-driver and then I ended up with the error:
File "<stdin>", line 1
import cassandra-driver
^
SyntaxError: invalid syntax
Also, when I do correct the hyphen issue with this:
__import__("cassandra-driver"), I get the error:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'cassandra-driver'
My which python3 is: /usr/local/bin/python3 and my which pip3 is: /usr/local/bin/pip3
My OS is MacOS
How to install cassandra?
Note: I am following this documentation.
Did you try to run these demos (from those docs)?
"If successful, you should be able to build and install the extension (just using setup.py build or setup.py install) and then use the libev event loop by doing the following:"
>>> from cassandra.io.libevreactor import LibevConnection
>>> from cassandra.cluster import Cluster
>>> cluster = Cluster()
>>> cluster.connection_class = LibevConnection
>>> session = cluster.connect()
There is a probability that actual module is named differently, e.g. there is another external package called Pillow, but you import it with name "PIL".
In docs they are importing from cassandra.cluster
Docs I'm referring to
$ echo 'import cassandra.cluster' > cassandra.py && python3 cassandra.py
Traceback (most recent call last):
File "./cassandra.py", line 3, in <module>
import cassandra
File "/home/xxx/cassandra.py", line 4, in <module>
import cassandra.cluster
ModuleNotFoundError: No module named 'cassandra.cluster'; 'cassandra' is not a package
Using a different filename, the error disappears:
echo 'import cassandra.cluster' > tmp.py && python3 cassandra.py
So, for me, the error was that my own program overrode the package. O.o
I have installed leptonica and tesseract in $HOME/local and tesseract is working properly, then tesserocr python package with:
CPPFLAGS="-I/home/user/local/include /home/user/local/lib" pip install tesserocr
and when I want to invoke it I get this:
$ python3 extract.py
Traceback (most recent call last):
File "extract.py", line 4, in <module>
from tesserocr import PyTessBaseAPI, RIL, PyLTRResultIterator, iterate_level
ImportError: liblept.so.5: cannot open shared object file: No such file or directory
please help
As mentioned in my comment on the original post, the proper installation command should be:
CPPFLAGS="-I/home/user/local/include -L/home/user/local/lib" pip install tesserocr
