Support for Jetson Nano

[gyillikci]

Hi,

When it comes to Jetson Nano/Xavier pip installation can cause problem. I somehow manage to install required dependencies yet, cant make it run the codes snippets.

Could you provide more detail into how it's not working? Is there an error? If yes, what is the error?

I created a virtualenv to isolate and install cython in addition to pip install vidstab (because there wasnt cython package available it needs to installed prior to pip install vidstab)

here is my env pip list

(videoStab) nano@nano-desktop:~$ pip list
Package         Version
--------------- ---------
certifi         2020.6.20
cycler          0.10.0

imutils         0.5.3
kiwisolver      1.3.0
matplotlib      3.3.2
numpy           1.19.2
Pillow          8.0.1
pip             20.2.4
progress        1.5
pyparsing       2.4.7
python-dateutil 2.8.1

six             1.15.0
vidstab         1.7.3
wheel           0.35.1

Here is my copy paste code from the readme named stabilization1.py

from vidstab import VidStab

stabilizer = VidStab()
stabilizer.stabilize(input_path=0,output_path='stable_webcam.avi',max_frames=1000,playback=True)

the error is below ; I tried with python3 and python just incase

(videoStab) nano@nano-desktop:~$ python stabilization1.py 
Traceback (most recent call last):
  File "stabilization1.py", line 1, in <module>
    from vidstab import VidStab
ImportError: bad magic number in 'vidstab': b'\x03\xf3\r\n'
(videoStab) nano@nano-desktop:~$ python3 stabilization1.py 
Traceback (most recent call last):
  File "stabilization1.py", line 1, in <module>
    from vidstab import VidStab
ImportError: bad magic number in 'vidstab': b'\x03\xf3\r\n'

I'll be honest in that I don't have experience with this error. Potentially this resource could be helpful.

Thanks for the suggestion Adam

After I delete .pyc files I uninstall the package and reinstall it. Now I encountered another issue regarding to csi camera

nano@nano-desktop:~$ python3 stabilization.py

Any approach to solve this issue?

@gyillikci , if you use a CSI camera, I think you should use gstreamer to access it with opencv. just a hint. But I think your error has nothing to do with this repo, I suggest you close this issue. There is nothing in this repo which is hardware specific, and it should definitely work on jetson, provided your opencv install is legit on the jetson.
