I'm using mac mountain lion(10.8.1) and python(2.7.3). And I want to use python matplotlib, numpy modules for figuring a graph.
But there's not matplotlib, numpy ver for mountain lion.
I've tested with matplotlib(1.1.1), numpy(1.7.0b1). They had been installed.
But it doesn't work like below. I just need a graph. Can mountain lion user draw a graph by python?

There isn't a specific "for Mountain Lion" numpy or matplotlib. The only compatibility consideration would be the python version, which in your case is fine. My guess is that you just need to force it to build in 64bit only:
ARCHFLAGS="-arch x86_64" pip install numpy

I assumed the issue was with the scipy because all the following errors come from that module. I checked and I have everything installed properly for the scipy module.
Please help! Thank you!
Run any command prompt you are using as administrator and then run pip install lib_name --force-reinstall
Try using these two commands they will help you:
conda remove --force scipy
And:
pip install scipy
Hello I had the same issue than you. Depend on wich version of python you use you should choose a version thinkx. I recommend you to go on the website of thinkx and check out for past udapte. In my case that was with matplotlib 3.3.1 for python 3.7. I went in git bash and used
pip install matplotlib==3.0.1
and everything worked. I had the same issue with seaborn and it worked.
I'm trying to use mayavi in python to visualize a pointcloud, and cannot resolve this error. I'm sure it is an easy pip install, but I am unsure of the command. Any help is much appreciated! Thanks!
BTW, I am running Ubuntu 18.04 and have tried installing scipy as mentioned here: Python import error "getfullargspec". I have also ran pip install traitsui. Additionally, I have rebooted my system.
Update:
After further digging, it appears that it may be an issue with Python versions. I was able to get it to run with Python3, but not Python 2.7 (I need it to work with python 2). I have also tried modifying the code within handler.py to getargspec instead of getfullargspec. I was given an error about trait_factory by doing this
Here is the entire printout:

The solution for this problem was to use older packages. Not all of the dependencies such as traitsui are compatible with Python 2.7. Even though an older version of mayavi was installed, the dependencies that are installed automatically are not compatible (they only support Python 3).
Here are the versions that work well together for me:
mayavi==4.6.2
traitsui==6.1.3
traits==5.2.0
numpy==1.17.4
pyface==6.1.2
To install a specific version, just run sudo pip install packageName==#.#.#
I'm trying to use Mayavi in Python 2.7, but cannot import it. My OS is Ubuntu (LTS). Here is the code:
import numpy
from mayavi.mlab import *
The following error is produced:

from traits.api import Property, Str, Undefined, implements
ImportError: cannot import name implements
I have tried force-reinstalling the packages mayavi, implements, traits, but to no avail. I tried both with pip and with apt.
Edit: I think the error is that mayavi cannot access VTK for my Python 2.7 installation. When I try to pip force-reinstall mayavi, I get the error "Could not find any downloads that satisfy the requirement vtk (from mayavi)". That error is described here. I do not know what to do, since both vtk and vtkpython are properly installed (with apt) and working - the issue is with mayavi and pip not knowing what to do?
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:

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.
I compiled matplotlib on a mac running snow leopard only to find that when I import matplotlib.pyplot I get the following error:

How do I fix this?
Building matplotlib on OS X is notoriously fraught with problems linking to mismatched versions of libraries that can be in the system directories, /usr/local, /opt/local, what have you. That's why there is a README.osx file in the source distribution advising you to use the make.osx file provided in the distribution that fetches and compiles the libraries and builds matplotlib against the fetched copy.
