_ufuncs.pyd loading error #745

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Hi,

I am experiencing the following error with SciPy in Python(x,y) 2.7.6.1:

from scipy.special import _ufuncs
ImportError: DLL load failed: The specified module could not be found.

I am running Windows 7 Professional 64-bit, Intel processor.

I didn't experience it with the previous version I was using, 2.7.5.0. For the 
installation, I just first uninstalled version 2.7.5.0 and the installed the 
new one.

On a AMD-based machine (exactly same OS), both versions 2.7.5.0 and 2.7.6.1 
work well, so I think it has to do with the processor, or the MKL-aware 
compilation.

Any idea?

Thanks!
Davide

This should be High Priority. Scipy integration routines are critical for 
scientific work. I did a clean install of python(xy)2.7.6.1 on a a 32-bit 
machine.  I had 2.7.3 and it was working okay for most things except IPython, 
so I decided to do a full install just to have a clean package.  After the 
installation I could not execute "from scipy import integrate". It traced back 
to missing _ufuncs in scipy/special.

Here's a copy of the directory and an execution of _testutils.py:

Please install the runtime support from:
https://software.intel.com/sites/default/files/managed/15/44/w_ccompxe_redist_ms
i_2013_sp1.3.202.zip
https://software.intel.com/sites/default/files/managed/c3/93/w_fcompxe_redist_ms

If the issue is resolved I'll bundle the above in the next xy version.

Hi,

I'm also experiencing a similar problem. I'm trying to use the savemat and 
readmat from the scipy.io library.
When I run the attached code I get the following error

import scipy.io as sio
  File "C:\Python27\lib\site-packages\scipy\io\__init__.py", line 85, in <module>
    from .matlab import loadmat, savemat, whosmat, byteordercodes
  File "C:\Python27\lib\site-packages\scipy\io\matlab\__init__.py", line 13, in <module>
    from .mio import loadmat, savemat, whosmat
  File "C:\Python27\lib\site-packages\scipy\io\matlab\mio.py", line 12, in <module>
    from .miobase import get_matfile_version, docfiller

  File "C:\Python27\lib\site-packages\scipy\special\__init__.py", line 546, in <module>
    from ._ufuncs import *

I have tried to do what grizzly.nyo posted in his second post without success.

I have also tried on a second computer and I don't face the same problem.

I have tried to use dependencyWalker to compare the missing DLL but there isn't 
any difference between the 2 computers.

Both machines run on windows 7 64 bits.

I would be very greatful for a solution!

Thanks 

James

can you please dump your CPU info? If you installed the Intel links from above 
you should be able to run the command below:

cpuinfo -A

Exactly as described in the comment #1, I have the follow error with SciPy in 
Python(x,y) 2.7.6.1:
from ._ufuncs import *
ImportError: DLL load failed: The specified procedure could not be found.

I am using Windows 7 (service pack 1) Professional 64-bit, Intel processor.

I have also installed the runtime as indicated in comment #2, but I have not 
yet solved this issue.

Any other idea?

"Windows XP is no longer supported."---that's non-responsive to the issue at 
hand because the Windows 7 people are having the same problem.  The package was 
working at one point.

Maybe (just maybe) you could use the data I gave to help solve the problem.

I have found the solution to fix the problem on my computer.

I used a dll fixer which then fixed/downloaded "LIBMMD.DLL". This dll should be 
placed in 

C:\Windows\SysWOW64

I hope this will solve the problem on other computer too!
