Cannot use socket

I am trying to import socket and I get the following error:
$ python
Python 2.7.16 |Anaconda, Inc.| (default, Mar 14 2019, 16:24:02)
[GCC 4.2.1 Compatible Clang 4.0.1 (tags/RELEASE_401/final)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import socket
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "socket.py", line 68, in <module>
from _ssl import \
ImportError: cannot import name RAND_egd
I thought that perhaps my Anaconda installation was corrupted so I uninstalled and reinstalled Anaconda but the error persists.
I had tried what the other posts suggested except for editing socket.py due to Macos System Integrity Protection. My guess is that the problem lies elsewhere as I doubt that everyone has had to edit the file.
How can I find the source of the problem?

import mlpack fails in python

I am trying to use mlpack in python scripts. I just installed the mlpack package from source into my directory /home/glassjawed/local/ and
glassjawed#Y9Acer:~$ ls local/lib | grep mlpack
libmlpack.so
libmlpack.so.3
libmlpack.so.3.0
glassjawed#Y9Acer:~$ ls local/include/mlpack/bindings/python
get_arma_type.hpp print_defn.hpp
get_cython_type.hpp print_doc_functions.hpp
get_numpy_type_char.hpp print_doc_functions_impl.hpp
get_numpy_type.hpp print_doc.hpp
get_param.hpp print_input_processing.hpp
get_printable_param.hpp print_output_processing.hpp
get_python_type.hpp print_pyx.hpp
import_decl.hpp py_option.hpp
mlpack strip_type.hpp
print_class_defn.hpp
So mlpack is clearly installed. HOWEVER, I can't seem to run this in python because I get a module not found error.

Why is this happening and how can I fix this? I tried everything.

Why do I get a ModuleNotFoundError for winreg on a Linux system?

'winreg' module is not found python 3.6.7. I am not facing this problem in Python 3.4.
Is any third-party app in 'winreg' that I can use same code or how can I solve this.

>>> from winreg import *
Traceback (most recent call last):

It is not work on linux because this package expose functions of the Windows registry API to Python

Intel DAAL python error

Intel Data Analytics Acceleration Library (Intel DAAL) has been installed successfully on my ubuntu. However, when running examples located at compilers_and_libraries_2017/linux/daal/examples/python/source/distance, I got following error. Anybody have this problem before?

I ran into the same problem. After I dig into the sample source, I found that it's due to the csv file path.
Just cd to compilers_and_libraries_2017/linux/daal/examples/python and run the sample again.

matplotlib: no module named compat

I have installed python-2.7.5-5ubuntu3 and matplotlib-1.3.1-1ubuntu5 from the ubuntu 14.04 repository via apt-get. Trying to import the library in python 2.7 raises the following import error:
harold#ubuntu:~$ python

from matplotlib.compat import subprocess
ImportError: No module named compat
>>>
I checked the directory /usr/share/pyshared/matplotlib and, indeed, cannot find any package called compat.
Any idea what is broken on my system?
Thanks!

I have found same problem on Ubuntu 16 & 14.
Possible source of the problem is damaged instance of matplotlib. Damaged instance overlaps working instance of matplotlib.
Please try to remove broken instance of matplotlib to solve the issue.
Firstly I have looked matplotlib instances:
find / |grep matplotlib | grep __init__\.py$ |more
Secondly I have deleted this folder:
find /usr/share/pyshared/matplotlib -delete
