while i try to run a matplotlib example program it shows "Failed to import numpy multicore array".Then i upgrade the numpy version from 1.12 to 1.15 on both the python versions 2.7 and 3.5(in raspberry pi python 2.7 is a default version).
The code am using is:
import matplotlib.pyplot as plt
plt.plot([1, 2, 3, 4])
plt.ylabel('some numbers')
plt.show()
while running this code it show some different error that
Traceback (most recent call last):

If you're working with a numpy git repo, try `git clean -xdf` (removes all

how to overcome this one?

I am trying to get arcpy to import in the vs code terminal (running python 2.7 as an arcgis install). It runs fine if I open a command window, initiate python, and import arcpy. It also works within the ArcGIS environment. This leads me to beloeve that the error below is inaccurate. Importing arcpy does not work at the VS Code terminal. How can I resolve this?

Im trying to package Anaconda with Tensorflow and Keras on Windows 10 for a class in our labs environment which the labs computers do not have administrator access nor do the students for security reasons.
Problem few lines of code to test to see if the installation is working correctly only work when you launch python as administrator:

I have a Python script which I want to start from cmd because I'm going to call it in a C# script.
The problem is, the code works fine in the IDE and when I call it from the Anaconda script but not when I call it from the regular cmd.
I'm calling the script with the following line:
$ python c:/Users/myname/pycharmProjects/testing/main.py
I get the following error message:

I have uninstalled and reinstalled numpy, but the error is still the same. I'm really confused why I it works via the Anaconda prompt, but not the cmd as I did set the PATH variable.
Any help is appreciated!
When I try to launch the application (.exe) file created by p2toexe, I receive the following error message:

When I ran the original Python script, no errors were raised with regard to importing nibabel.
In response to #Sagar's comment:
The import in the file Main_GUI.m:
from __future__ import print_function
import matplotlib.pyplot as plt
from matplotlib import widgets
import numpy as np
import nibabel as nib
import matplotlib as mpl
import time
import os
there was a problem of compatibility between the modules versions (py2exe==0.6.9 and nibabel==2.2.0).
It works with py2exe 0.6.9 and nibabel 2.1.0.
The problem is likely a configuration issue, because getting the installation correct on Macs seems to be tricky. I'm running Mavericks and matplotlib 1.4.x, yet when I open a Python 2.7.5 shell and import pylib, I get this error:

Reason: image not found
I have libpng16 installed, but not libpng15.
I saw a hardcoded reference to libpng15 in _png.so.
Uninstall and install of matplotlib fixed the issue for me.
You can always moke it by generating a soft link like this
sudo ln -s /opt/X11/lib/libpng.dylib /usr/local/lib/libpng15.15.dylib
Not the cleaner solution but I haven't figure out why matplotlib stubbornly asks specifically for libpng15 and not any 15 or greater.
