I installed PLS extension bundle for my SPSS26. I got Python27. Installed numpy and scipy for my python version and set the python2 path on SPSS to the path of python2 having numpy and scipy in my C directory. Still on running PLS, I am getting the following errors:

Extension command PLS could not be loaded. The module or a module that it requires may be missing, or there may be syntax errors in it.

Kindly help me.

Thanks,

Shilpi

If you downloaded PLS recently, it would be a Python 3 version, so you would need to use Python 3 versions of numpy and scipy.

Try running this code in a syntax window to get a more precise error message.

begin program python3.

import PLS

end program.

You might also want to install a version of PLS from here

as the initial conversion to Python 3 had some problems. I don't know whether the currently posted version has the fixes.

Thanks for your reply. Yes it appears that the python 2 versions of scipy are not being read by SPSS. Hers's what I got:

begin program python3.

import PLS

end program.

Traceback (most recent call last):

File "C:\\ProgramData\\IBM\\SPSS\\Statistics\\26\\extensions\PLS.py", line 81, in <module>

from scipy import *

ImportError: No module named 'scipy'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):

File "<string>", line 2, in <module>

File "C:\\ProgramData\\IBM\\SPSS\\Statistics\\26\\extensions\PLS.py", line 83, in <module>

if not e.message.startswith("cannot import name"):

AttributeError: 'ImportError' object has no attribute 'message'

EXTENSION /SPECIFICATION COMMAND='C:\ProgramData\IBM\SPSS\Statistics\26\extensions\plscommand.xml'.

However, my SPSS26 has Python 3.4 associated with it. So does that mean I install a separate Pyhon3.4 version somewhere else and then put it in the path of SPSS?

Thanks,

Try installing 3.4 somewhere and then installing numpy and scipy for that version. Then set that external 3.4 as the version for Statistics to use via Edit > Options > Files

Support Member​  IBM SPSS Statistics 27.0 and now 27.0.1 requires Python 3.8. You should be able to install a separate (external) Python 3.8 from python.org. Then install numpy and scipy via command line:

>python3.exe -m pip install numpy scipy

Hi,

I installed Python3.4. Then when trying to install numpy I am getting the following error:

C:\Python34\Scripts>pip install C:\Downloads\numpy-1.16.6 mkl-cp34-cp34m-win_amd64.whl

Thanks

That makes me wonder whether you actually are running 3.4 materials, because the typing module was new in Python 3.5, but try doing a pip install of typing.
