ImportError: No module named 'LeapPython'

[geoffpeters]

Hello... Can anyone offer a suggestion??

Addendum, this is on a Windows 10 machine...

I'm trying to run the Sample_P3.py script for the first time. I had to change the import statement by removing Leap, adding inspect, and changing thread to threading.

When I try to run it I see this:
Traceback (most recent call last):
File "../lib\Leap.py", line 18, in swig_import_helper
fp, pathname, description = imp.find_module('LeapPython', [dirname(file)])
File "C:\Python37\lib\imp.py", line 296, in find_module
raise ImportError(ERRMSG.format(name), name=name)
ImportError: No module named 'LeapPython'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
File "Sample_P3_gp.py", line 22, in
from Leap import CircleGesture, KeyTapGesture, ScreenTapGesture, SwipeGesture
File "../lib\Leap.py", line 28, in
LeapPython = swig_import_helper()
File "../lib\Leap.py", line 20, in swig_import_helper
import LeapPython
ImportError: DLL load failed: %1 is not a valid Win32 application.

I would appreciate any assistance.

Thanks.

OK, so I was unable to get the Python 3 version to run. Now I can at least successfully start the Sample.py script with Python 2.7.

But, I only get as far as seeing:
Initialized
Press Enter to quit...

And no data.

I would appreciate any clues someone can offer.

Thanks

What version of the core software are you running?

[geoffpeters]

Thanks for the reply. I'll let you know later today. Just to be clear, where do I find that? I'm not at the location where I have it set up.

[AlexColgan]

You'd be able to see it by right clicking on the taskbar icon, going to settings, and then the About tab. If you can point me where you downloaded it from, and when, I could also tell you

[geoffpeters]

Thanks, I can check this afternoon. I believe it's version 2.3.1 but I'll confirm that later.

[geoffpeters]

Hi Alex,

I'm using version 2.3.1.31549. By the way, I do not know what taskbar icon you are referring to.

Just to clarify, the "Initialized Press Enter to quit" was the response when I tried to run the script from Idle. I did not try PyCharm.

I did try both the Sample.py and the Sample_P3.py files from powershell and I see this:
PS C:\leapsdk\leapsdk\samples> python Sample.py
Traceback (most recent call last):
File "Sample.py", line 9, in

File "C:\Python37\lib\imp.py", line 342, in load_dynamic
return _load(spec)
ImportError: Module use of python27.dll conflicts with this version of Python.

I have both Python 2.7 and Python 3.7 Available.

Thanks,
Geoff

Hi can you offer any assistance? It has been a number of days and I have heard nothing.

Help!

Thanks

On the scripting side unfortunately there is not much that I can suggest, given that you're using the right version; I do know that our SDK only supports up to Python 2.7.3.

On the data side... the taskbar icon is located in your taskbar, on the lower right-hand side. It's a green icon, and when you right-click on it, you should see Visualizer as an option. When you open it, are you able to see the hands tracking properly?

[geoffpeters]

Well, there is a Sample_P3.py file. I wonder why that's there if there is no support for Python 3?

It is possible that I downloaded the SDK 3.2 beta. Perhaps I should uninstall that? I would really like to use Python 3, but if it's not fully supported maybe I should stick with version 2.

I any case I was not running the visualizer, hence no icon.

I'm just trying to understand how to grab data from the controller and I thought the sample file would be a good place to start.

What do you suggest?

Thanks

[AlexColgan]

Can you confirm that the hands are tracking properly in the visualizer?

[geoffpeters]

Yes, for the most part. I have had a couple of instances where the position of the hands was mirrored. But usually the tracking is good.
