numpy multicore error while using matplotlib

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):

During handling of the above exception, another exception occurred:

ImportError:
Importing the multiarray numpy extension module failed. Most
likely you are trying to import a failed build of numpy.
If you're working with a numpy git repo, try `git clean -xdf` (removes all
files not under version control). Otherwise reinstall numpy.
Original error was: libf77blas.so.3: cannot open shared object file: No such file or directory
how to overcome this one?

Scipy won't install properly installation

I'm trying to install Scipy through pip, but it won't work. It says that it already is installed, but when I try to import the modules it gives me errors.
from matplotlib import pyplot as plt
Error:

ImportError: cannot import name 'rcParams'
EDIT: It turned out, that the problem was, that I called my file "matplotlib.py".

Turned out that I was super stupid, and I just had to rename the python file to something else than "matplotlib.py" since it confused the script.

import error but in the program init, can someone help me? (Python 2.7.14)

I have those errors when i'm trying to import the matplotlib.
How can i fix this?
I have install matplotlib with the pip install matplotlib and this was a succes.
But when i import the package i have this kind of error.
i see it is in the init block but how can i fix this?
i have already tried the pip matplotlib upgrade but this keeps the same problem.
i just have matplotlib uninstalled and back installed and it is the same problem.

I have tried another code, that I found in the comments. But this generate my another error code.

A "p" seems to be missing from "pyplot". You have pylot instead of pyplot in the import statement.

ImportError: cannot import name 'rcParams' on python 3.4 win 10

Have installed win 10 on my macbook for working with different plot libraries in python 3.4. I began vs Tkinter, but it is boring, so I followed some forums-speakers and tried matplotlib. I installed it using pip3 and get next error:

ImportError: cannot import name 'rcParams'
in simple task:
import matplotlib.pyplot as plt
plt.plot([1,2,3])
plt.ylabel('some numbers')
plt.show()
what should I do to make it work?
can you give me some advises in plot libraries for science? Im looking for more 2D than 3D plotting libraries.

Problems with matplotlib

I'm trying to make a graph using matplotlib.pyplot and subprocess, but I get the following error:
Traceback (most recent call last):
File "subprocess.py", line 2, in <module>
import matplotlib.pyplot as plt

from matplotlib import _pylab_helpers, interactive
ImportError: cannot import name _pylab_helpers
If I try to do a graph not using subprocess (just plotting 2 arrays as axes), I don't get this problem.
Can someone help me?
