ImportError: libgstbase (and other missing dependencies)

I have followed your guide, but I cannot get the Python scripts to run successfully.

This was a fresh installation of Rasbpian Lite (Buster, 2020-02-13). All steps attempted twice with a re-image between.

Some dependencies were missing from the guide, which I took as assumed knowledge:

sudo apt install -y git python3 python3-pip python3-venv python3-opencv
pip3 install opencv-python

They only got me so far. I can't seem to get past this one:

python3 TFLite_detection_image.py --modeldir=Sample_TFLite_model --imagedir=.
Traceback (most recent call last):
  File "TFLite_detection_image.py", line 18, in <module>
    import cv2
  File "/home/pi/tflite1/tflite1-env/lib/python3.7/site-packages/cv2/__init__.py", line 3, in <module>
    from .cv2 import *
ImportError: libgstbase-1.0.so.0: cannot open shared object file: No such file or directory

I don't know much about Python and nobody else has cited these issues, so I suppose I must be missing something.

@devopsleigh I ran into the same issue and for anyone else running into this again, this should resolve it.

Hi, I successfully ran project on Rasp on first try. All worked But after restart it gives import cv2 error

followed https://github.com/EdjeElectronics/TensorFlow-Lite-Object-Detection-on-Android-and-Raspberry-Pi/issues/63#issuecomment-703019851 but appears all sets are available

If run pip3 show opencv-python Gives Version: 3.4.6.27

Is there any idea? Thanks
