Hello! I tried to run Numpy with Jython via JyNI, as described in a paper https://arxiv.org/pdf/1607.00825v1.pdf
1) I copied Numpy package from separately installed Anaconda-2 into C:\jython2.7.2\Lib\site-packages\, due to a problem with installing Numpy by Jython pip (see https://bugs.jython.org/issue2928 )
2) I unpacked DemoExtension.pyd and python27.dll from JyNI archive into C:\JyNI folder.
3) I tried to run a very simple code:
import sys
sys.path.append('c:/JyNI')
import numpy as np
(as written in PDF-file).
Results:
Traceback (most recent call last):
File "C:/siams/computer-vision/stare-python/jython-experiments/net/algart/jython/tests/SimpleJythonNumpyTest.py", line 3, in <module>
import numpy as np
File "C:\jython2.7.2\Lib\site-packages\numpy\__init__.py", line 142, in <module>
from . import core
File "C:\jython2.7.2\Lib\site-packages\numpy\core\__init__.py", line 71, in <module>
raise ImportError(msg)
ImportError:
IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!
Importing the multiarray numpy extension module failed. Most
likely you are trying to import a failed build of numpy.
Here is how to proceed:
- If you're working with a numpy git repository, try `git clean -xdf`
(removes all files not under version control) and rebuild numpy.
- If you are simply trying to use the numpy version that you have installed:
your installation is broken - please reinstall numpy.
- If you have already reinstalled and that did not fix the problem, then:
1. Check that you are using the Python you expect (you're using C:\jython2.7.2\bin\jython.exe),
and that you have no directories in your PATH or PYTHONPATH that can
interfere with the Python and numpy versions you're trying to use.
2. If (1) looks fine, you can open a new issue at
https://github.com/numpy/numpy/issues. Please include details on:
- how you installed Python
- how you installed numpy
- your operating system
- whether or not you have multiple versions of Python installed
- if you built from source, your compiler versions and ideally a build log
Note: this error has many possible causes, so please don't comment on
an existing issue about this - open a new one instead.
Original error was: No module named _multiarray_umath
What does go wrong here? Is it a problem of using module "numpy" from Anaconda (instead of normal installing with pip), or is it a problem if using JyNI? |
