I installed ros1 and created a catkin workspace. Inside the src folder I cloned a ros package "executive_smach_visualization". But when I try to run it with the following command I am getting an error.
rosrun smach_viewer smach_viewer.py
Traceback:

import gobject
ImportError: No module named gobject
I have already tried following:
1) Installed goobject using pip
2) cloned gobject from git to src folder of catkin_ws, catkin_make and setup.bash
What could be the problem? Please let me know if I am missing any important input. Thanks in advance.
This issue occurs if there is different version of ros, python and so on.
It seems package is a little bit outdated.
Edit:
After downloading package and when building your working environment, use:
catkin_make -DPYTHON_EXECUTABLE=/usr/bin/python2 -DPYTHON_INCLUDE_DIR=/usr/include/python2.7 -DPYTHON_LIBRARY=/usr/lib/libpython2.7.so
Please refer to 1.5 section (User configuration) of this guide

I can't figure it out what is the problem. I use python 3.7. I saw on the internet a similar issue on windows, but not on mac. I would be really grateful if you could help me.
You seem to have a broken installation of the brotli module (missing its native code component _brotli).
Try uninstalling it with pip uninstall brotli, then reinstall it; pip install brotli.
Going forward, I would heavily recommend you learn and use virtualenvs instead of installing everything into your Python's site-packages.
After uninstalling and installing again brotli it worked! Moreover, working in virtual environments is really more appropriate. Thank you a lot, AKX.
I have multiple Python versions installed with pyenv on Ubuntu 16.04. I create virtual environments to work with projects using different versions with pipenv. However, for Python 3.5.x only I get errors like this when I try to edit a file with Vim 8 (installed via the PPA) in an activated virtualenv:
"test.py" 49L, 1434C

The issue seems to affect all python related Vim plugins. With other Python versions (e.g. 3.6.x, 3.7.x) this does not occur. What may be causing this issue?
Update: It seems that when I run Vim inside a 3.5.x virtualenv, the Vim's interpreter's sys.path gets updated somehow. For example, this is the output of :py3 import sys; print(sys.path) inside a 3.6.0 virtualenv:
['/usr/lib/python35.zip', '/usr/lib/python3.5', '/usr/lib/python3.5/plat-x86_64-linux-gnu', '/usr/lib/python3.5/lib-dynload', '/usr/local/lib/python3.5
/dist-packages', '/usr/lib/python3/dist-packages', '_vim_path_']
And this is for 3.5.3:

The issue can be reproduced in a ubuntu:16.04 docker container.
Debian Bug report logs - #852163: python3.5-minimal wont configure demonstrates that this error (for Python 3.5 and Python 3.6) is due to another incompatible installation of Python in /usr/local.
Some further digging with another user in #debian who was experiencing this
problem indicated that it was related to a locally installed
/usr/local/bin/python3.5. The stdlib in /usr/lib/python3.5 is picked up by the
/usr/local/bin/python3.5 but is not compatible with it, resulting in the
stacktrace shown.
Removing /usr/local/bin/python3* and all traces of that installation from
/usr/local/lib (plus other associated tools) solved this problem for the user
I was helping in #debian.

The problem is caused by the system installed python, which conflicts with personally installed python.
It could be the case that other python versions are interfering here. Do you have a PYTHONPATH set?
echo $PYTHONPATH
If it is set you could try to unset it. It's usually not needed when using virtual environments.
Try running python with sudo. I think the python which comes with OS needs to run with admin privilege.
I'm using Anaconda3 version 4.2.0 on ubuntu (in docker).
Anaconda is installed in /root/anaconda3 folder.
I installed theano_bpr package using pip install theano_bpr.
Now when i open python and try import theano_bpr, i get the following message:
>>> import theano_bpr
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/root/anaconda3/lib/python3.5/site-packages/theano_bpr/__init__.py", line 17, in <module>
from bpr import BPR
ImportError: No module named 'bpr'
However, when i navigate to /root/anaconda3/lib/python3.5/site-packages/theano_bpr/ and run python there, i'm able to import theano_bpr.
In /root/anaconda3/lib/python3.5/site-packages/theano_bpr/ there are following files:
__init__.py, bpr.py (this one is causing problems), t.py, and utils.py.
I usually code in Matlab but I found a nice piece of PYTHON code that I would like to use. However having downloaded the package it is proving difficult to run. I'm getting the following error:

The _ufuncs.pyd is there in the C:\Python34\lib\site-packages\scipy\special\ directory. I tried adding this to my PYTHONPATH but it made no difference. I have also tried so dll fixers but these have not helped.
Has anyone encountered this and did you find a solution?
As other have said, make sure your .whl file matches the version and 32/64bit of the python distribution you're using.
Next, the problem I was having was I forgot to download and install the extra "numpy+mkl" package per the instruction: http://www.lfd.uci.edu/~gohlke/pythonlibs/#scipy
So for me it was numpy-1.11.0+mkl-cp35-cp35m-win_amd64.whl, which I downloaded and then:
python -m pip install numpy-1.11.0+mkl-cp35-cp35m-win_amd64.whl
I had already installed the regular numpy package via pip, but I just installed this one over it and everything started working and has been fine so far.
I wanted to installed logilab-common 0.61.0 on to my computer I am a windows user and my python version i 27. Whenever I import the module it throws me the error
Traceback (most recent call last):
File "<pyshell#0>", line 1, in <module>
import logilab
File "logilab\__init__.py", line 28, in <module>
from logilab.common.__pkginfo__ import version as __version__
ImportError: No module named common.__pkginfo__
However I checked this file exists. Also when I try to call Pylint (the reason I installed logilab) from command line it throws import error
Loaded Module logilab not not found in sys.modules
I also tried to reinstall logilab and logilab astng. I do not If its a compatibility issue perhaps?
You probably have two distinct installation of the logilab package, one for logilab-common and the other for logilab-astng. Take a look at:
import logilab
print logilab.__path__
You should fix things (adjust PYTHONPATH?) so that you get the directory containing the common subdirectory there.
Also notice that for recent version of pylint (>= 1.0), logilab-astng has been replaced by astroid.
