Mingus/lilypond on python

I can import mingus but sublibraries such as mingus.extra.lilypond give me an error:
import mingus.core.notes
Traceback (most recent call last):
File "<pyshell#4>", line 1, in <module>
import mingus.core.notes
File "C:\Users\PharaohZz\AppData\Local\Programs\Python\Python36\lib\site-packages\mingus\core\notes.py", line 29, in <module>
from mt_exceptions import NoteFormatError, RangeError, FormatError
ModuleNotFoundError: No module named 'mt_exceptions'
or
import mingus.extra.lilypond
Traceback (most recent call last):
File "<pyshell#2>", line 1, in <module>
import mingus.extra.lilypond
File "C:\Users\PharaohZz\AppData\Local\Programs\Python\Python36\lib\site-packages\mingus\extra\__init__.py", line 20, in <module>
import lilypond
ModuleNotFoundError: No module named 'lilypond'

You can fix this problem by first uninstalling mingus (pip uninstall mingus).
Then build the library from it's source. To do this:
Download the files from git hub using the command git clone https://github.com/bspaans/python-mingus .
Enter the directory using cd python-mingus.
Finally install it using the command python setup.py install.
This fixed the problem for me.

AttributeError: module 'mxnet' has no attribute 'io'

trying to run this project
and got an error when typing:
python demo.py --gpu 0
on my terminal
the error:
Using mxnet as:

(export MXNET_EXAMPLE_SSD_DISABLE_PRE_INSTALLED=1) to prevent loading pre-installed mxnet.

Looks like the author doesn't want you to use a different version of MXNet than what is included in the project. I see that MXNet is included as a submodule in the project. You should do a recursive clone of the project (git clone --recursive https://github.com/zhreshold/mxnet-ssd.git) and use the version of MXNet that comes with the project.
Remember to export MXNET_EXAMPLE_SSD_DISABLE_PRE_INSTALLED=1 like mentioned in the comments.

Linux undefined symbol _mkdir in the .so file of swmm5 python package

I am new to python and Linux. I installed swmm5 package in Linux by downloading the source SWMM5-5.1.0.102.zip:
python setup.py install
Before typing the previous syntax to install swmm5, I have unquoted #define CLE and deleted #include <direct.h> in the file swmm5.c, otherwise the installation won't succeed.
Then I tried to test the swmm5 package and get the following error:
from swmm5.swmm5tools import SWMM5Simulation
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/home/pyangac/Py_libs/lib64/python/SWMM5-5.1.0.102-py2.7-linux-x86_64.egg/swmm5/swmm5tools.py", line 1, in <module>

import _swmm5
ImportError: /home/pyangac/Py_libs/lib64/python/SWMM5-5.1.0.102-py2.7-linux-x86_64.egg/_swmm5.so: undefined symbol: _mkdir
I have also installed the swmm5 package in Window, and the similar testing process gets no error.
Is there anyone understand what's going on and what should I do to use the swmm5 package in Linux? Thanks.

Python: pip is installed but not working in windows

I have installed python 3.6.0, you don't need to install pip manually if you are using python (>3.3). But When I am trying to access pip (pip --version), it throws me two errors which mainly relate to not finding the module.
Description is given below.
C:\Users\sharma6>pip --version
Traceback (most recent call last):
File "c:\python360\lib\site-packages\pip\_vendor\requests\packages\__init__.py", line 27, in <module>
from . import urllib3

During handling of the above exception, another exception occurred:

File "c:\python360\lib\site-packages\pip\_vendor\requests\packages\__init__.py", line 29, in <module>
import urllib3
ModuleNotFoundError: No module named 'urllib3'
Even when I import socket (>>>import socket)in python interpreter , It shows me "Can not found the module" error .
>>> import socket
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\python352\lib\socket.py", line 49, in <module>
import _socket
zipimport.ZipImportError: can't find module '_socket
Could someone tell me about the errors and how to resolve them because I need pip to work properly.

Add your all path in your system variable instead of adding in user variable.
It worked for me!!! :)

You should try to write
python -m pip --version
If this gives an error message, install pip by downloading get-pip.py from https://pip.pypa.io/en/stable/installing/ and install with
python get-pip.py
Installing with pip is then done by
python -m pip install [package name]

Having issue with python pip command

I had python pip installed and it was working fine but I did something wrong now it is broken.
Now when I execute pip command to install new packages, I get an error.
like if execute pip list then I get the below error.
root#dragonwarrior-Latitude-3440:~# pip list
Traceback (most recent call last):
