Python import error no module named bz2 - python

I have libbz2-dev installed however I am still getting the following import error while importing gensim :
>>> import gensim
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/home/krishna/gensimenv/lib/python2.7/site-packages/gensim/__init__.py", line 6, in <module>
from gensim import parsing, matutils, interfaces, corpora, models, similarities, summarization

import bz2
ImportError: No module named bz2

you can try to do
pip install bz2file

I'm having the same issue and the tip above didn't resolve it.
Perhaps before creating the virtual env you need to:
sudo apt-get install libbz2-dev

Python modulenotfound error - Is there a "pip" alternative way to install python modules

I am trying to run a program (obviously written in python) and it requires some python modules. One of the missed modules is aiomultiprocess. I tried installing it with pip install aiomultiprocess pip3 install aiomultiprocess python3.7 -m pip install aiomultiprocess but they all come back with the same error message:
Traceback (most recent call last):
File "<string>", line 1, in <module>

import ffi
ModuleNotFoundError: No module named 'ffi'
No ffi module?! Let's get it!
I looked it up and figured it's a foreign library that come, in the case of python, as 2 forms: CFFI & LibFFI, but "ffi" doesn't exist for python. I installed cffi libffi and added them to this path /usr/local/lib/python3.7/site-packages/, but it changed nothing.
So my question is there another way to install python modules without the need of pip??!

ImportError while running python program

I have tried all the import methods and upgrading the libraries but still I'm unable to get over this error. I have downloaded and installed all the nltk and corpus data programmatically and it is working in the python shell but i'm getting error.
Traceback (most recent call last):
File "spark.py", line 7, in <module>
from textblob_aptagger import PerceptronTagger
File "/usr/local/lib/python2.7/dist-packages/textblob_aptagger/__init__.py", line 8, in <module>

from textblob.packages import nltk
ImportError: No module named packages
Here's a pastebin to my code and imports..
Same error has been posted on github here. Use this instead to install textblob:
$ pip install -U git+https://github.com/sloria/textblob-aptagger.git#dev
Also, you should change from text.blob import TextBlob as tbto from textblob...
Works for me..

ImportError: No module named 'numpy.ma'

The full error:
import matplotlib
Traceback (most recent call last):
File "<pyshell#0>", line 1, in <module>

import numpy.ma as ma
ImportError: No module named 'numpy.ma'
numpy is imported normally.
How do I install numpy.ma?
I also faced the same situation today. I found that I had saved a file as numpy.py, so check the filenames in your folder.
Re-install the correct version of numpy.
download correct .whl file from http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy
pip install C:\Path\To\Wheel\Filename.whl # for example: numpy-1.9.2+mkl-cp34-none-win_amd64.whl
Use Your (via terminal) package manager and search.
Example on Ubuntu:
aptitude search numpy
and install package.
In my case:
apt-get install python-numpy

py2neo offline install failing

I'm trying to install py2neo on an offline machine. I can't use pip because I'm not connected to the internet. I'm trying to install py2neo-2.0.3 with python2.7.9 on redhat. When I run python setup.py install I get ImportError: cannot import name HTTPSConnection.

I've tried installing httpstream but that didn't fix the import error.
HTTPSConnection should come with the standard library and isn't part of py2neo itself:
https://docs.python.org/2/library/httplib.html#httplib.HTTPSConnection
I don't know specifically about how RedHat package Python but it's possible you need to install SSL support in addition to the main language. I believe this is a separate compilation option:

Getting errors when trying to import pymc

I have installed pymc using easy_install pymc command. While I try to import the package using import pymc.

ImportError: libatlas.so.3gf: cannot open shared object file: No such file or directory
I am using Ubuntu 12.04 and Python 2.7.
What is the reason for these errors?
Try installing that missing library:
apt-get install libatlas3-base-dev
