I would be grateful if anybody can help.
Thanks.
If you actually install rdflib via pip, then its dependencies will come along with it (isodate included):
pip install -U rdflib
or
easy_install -U rdflib
Chances are you might have installed it directly from source, meaning you would have to take care of the deps yourself.
Information on installing pip if you dont have it already:
http://www.pip-installer.org/en/latest/installing.html
If you have easy_install, you can do: easy_install pip
It seems there is a dependency to isodate, so try installing that via your favorite PyPI-Installer (pip oder *easy_install*).

I want to install a package called Xsequence https://github.com/fscarlier/xsequence
in Windows vie git clone command and then I used python to install it
git clone https://github.com/fscarlier/xsequence.git
cd xsequence_master
python setup.py install
I have several python versions installed, put the one that was used in the installation was in the first path.
C:\Users\musa\AppData\Local\Programs\Python\Python310\python.exe
C:\Users\musa\Anaconda3\python.exe
C:\Users\musa\AppData\Local\Microsoft\WindowsApps\python.exe
The issue is that when I import the package Xsequence it works fine,
But when I try to import any other module from inside this package it doesn't work

I checked the package folder manually it contains the module Xsequence.helper.
The strange thing that all the module can be imported if I run python directly after instilling the setp.py but once I closed the terminal its not imported anymore
I am completely new to Python but I enjoyed it very much. I start with Python 2.7 before migrating to Python 3 since many applications for work have to do with Python 2.7.
I have quite sadly many version of python2.7 on my MacBook. One from Apple, one from Homebrew, one from Anaconda. I have pip version 18.0 installed.
I wanted to install many modules (scipy in particular) and I ran into the following problem.

I get the error message:

I looked on the web and found the solution for that by typing:
pip install --user matplotlib
Now when I do:
>>> import matplotlib
I get the message:

There is a confusion on the web about how to solve this problem. Is there still hope I can get back running?
I am trying to use python-mbus for python 3, i have installed it with

Im runnin on Debian GNU/Linux buster/sid
Any idea of what am I doing wrong?
I'm not exactly sure how I fixed this (can't comment), but I had the exact same problem and I did:
sudo pip3 uninstall dbus-python
sudo aptitude update && sudo aptitude upgrade
sudo aptitude -f
After which aptitude alerted me of some dependency issues with Python, and I "downgraded" a version of Python I had installed on Ubuntu Xenial to the default package provided by Artful. Now, import dbus on Python 3.6.3 doesn't pass any errors. Don't know if it actually works well, though.
Maybe you'll be able to fix it in a similar fashion, since Debian and Ubuntu packages are usually the same.
I have installed installed the following modules in my EC2 server which already has python (3.6) & anaconda installed :
snappy
pyarrow
s3fs
fastparquet
except fastparquet everything else works on importing. When I try to import fastparquet it throws the following error :

How do I go about fixing this ?
Unfortunately, there are multiple things in python-land called "snappy". I believe you may have the wrong one, in which case one of the following conda commands should solve this for you:
conda install python-snappy
or
conda install python-snappy -c conda-forge
where the latter is slightly more recent (releases the GIL which can be important in threaded applications).
I have installed mechanize library for python3.
https://github.com/adevore/mechanize/tree/python3
But, when I import it, I get this error.

$ pip freeze

I'm not used to operation in terminal, so I don't know how to fix this problem.
Could anyone please help me solve this problem?
Thank you in advance!
The git repository you referred to uses import wrong. The mechanize._html module imports _sgmllib_copy expecting to get mechanize._sgmllib_copy, but that way of doing imports has been deprecated in PEP 328. Rather it should be using relative imports, e.g. from . import _sgmllib_copy.
https://github.com/adevore/mechanize/tree/python3
This branch doesn't contain _sgmllib_copy.py at all. I took this file from master branch (it needs to change print smth to print (smth)). But I still don't get how import should be used. In _html.py module (it's located in mechanize folder) used
from . import _sgmllib_copy as sgmllib
Is this wrong? But from . import _beautifulsoup seems to be working.
