How to install numpy in Maya?

Anonymous — Fri, 22 Dec 2017 13:47:48 GMT

Hi, I have some problems when installing the numpy in Maya 2015. How to install this python package correctly?

I've used easy_install for this python package. The commands in Windows cmd are written as:

"...\Maya2015\bin\mayapy.exe ...\setyptools-38.2.4\easy_install.py numpy". More details are referred in http://jensvhansen.com/installing-new-packages-for-maya-python/

I notice that the numpy folder is installed at "...\Maya2015\Python\Lib\site-packages\numpy_1.14.0rc1-py2.7-win-amd64.egg". But when I entered "import numpy" in mayapy.exe, it turner out that "Original error was: DLL load failed: %1 is not a valid Win32 application."

When I enter the "Import numpy" in Script Editor in Maya, the information shows that:

"# Error: line 1: Error in maya.utils._guiExceptHook:
# File "E:\Program Files\Autodesk\Maya2015\Python\lib\site-packages\maya\utils.py", line 318, in formatGuiException
# exceptionMsg = unicode(exceptionObject.args[0])
# UnicodeDecodeError: 'ascii' codec can't decode byte 0xb2 in position 298: ordinal not in range(128)

# Original exception was:
