integrating WHL Python packages

Hi, as far as i can understand from the documentation and examples here in the community - TC supports integrating external Python libraries using EGG files, which is a very old (since 2004) format....

    Just to close the loop and save time for future users with the same problem, the solution is as followed:

    1. open the WHL file with 7-zip

    2. extract the folders in it to "C:\Program Files (x86)\SmartBear\TestComplete 12\Bin\Extensions\Python\Python36\Lib\site-packages" folder.

    3. add these lines to the start of your code:

     

    import sys

    sys.path.insert(0, 'C:\Program Files (x86)\SmartBear\TestComplete 12\Bin\Extensions\Python\Python36\Lib\site-packages'

    import <your lib name (in my case: numpy)>

     

    that worked like a charm.

Yeah,  i read that page many times looking for clues..

That's why i specified the community examples as well..

There it's only egg files.

 

Anyway, this whole procedure is not "normal Python stuff" because this is not how Python external libraries are installed.

 

Also, like i said - i'm not sure if it's an egg\whl issue, or some other limitation to integrate complected Python libraries..

 

Is there anyone here who knows how does this import really work?

So... what's not working for you?  I've seen folks importing packages here that are WHL so I know that works.  Are you getting errors? If so, what errors?

 

As for the community example... that's one example where someone is using EGG... Again, others are using WHL so those are working.

 

so... bit more information from you... what have you attempted (code examples from your TestComplete project would be helpful), version of TestComplete you're using, version of Python, any error messages you're getting, etc.

    OK.. your right - i kind of started from the middle here..

    so here it is:

    i'm using the latest TC ( 12.50.4142.7) and running it with the X86 version.

    No Python installed other than the one supplied by TC.

    I've put the whl file in the site-packages folder as needed. (the regular bin, not the X64 one, since i'm using the X86)

    my code:

     

    numpy_location = 'C:\\Program Files (x86)\\SmartBear\\TestComplete 12\\Bin\\Extensions\\Python\\Python36\Lib\site-packages\\numpy-1.14.5-cp36-none-win32.whl'
    from os import sys
    sys.path.insert(0,numpy_location)

    import numpy as np

    def test():
         a = [1,2,3]
         b = np.array(a)
         print(b)

    when i ran it - i've stopped with breakpoint before this line:

    b = np.array(a)

    just to make sure that there are no errors before that line, and everything was ok.

    but running this specific line (which is the must basic and simple action you can do with the numpy library), i get this error (screenshot attached as well):

    Import error: Importing the multiarray numpy extension module failed. Most likely you are trying to import a failed build of Numpy

    .

    Just to make sure - i've redownloaded that file again and also made sure that it worked fine on another PC without TC.

     

    thanks again.

    Nadav.

    Nadav I got a notification via e-mail that you replied but your reply is not showing up.

     

    In your reply, you indicate that you're including the whl file name in your sys.path.  First of all, if you're copying your file into TestComplete's environment, you shouldn't need the sys.path.insert line of code as per https://support.smartbear.com/testcomplete/docs/scripting/specifics/python.html#importing-packages.  If that doesn't work, replace your line of code with below... essentially, for importing packages, the path should be, simply, the path and not the actual file name (whl or egg).

     

    Change this line of code:

    numpy_location = 'C:\\Program Files (x86)\\SmartBear\\TestComplete 12\\Bin\\Extensions\\Python\\Python36\Lib\site-packages

      removing the file name from the path did not help - i get this error:

      Python runtime error.
      
ModuleNotFoundError: No module named 'numpy'

      same when removing the insert to location.
