Dependency error even after adding libglib2.0-0 to package.txt

Even after adding the libglib2.0-0 to package.txt I still get this error:

Traceback (most recent call last):

  File "/home/appuser/venv/lib/python3.7/site-packages/streamlit/script_runner.py", line 333, in _run_script

Hi @saaranshM, welcome to the Streamlit community!!

To resolve the error:

• Replace opencv_python==4.2.0.34 with opencv-python-headless in your requirements.txt file
• Delete packages.txt
• Reboot your app

Once you’ve made the changes, your app should deploy successfully!

Happy Streamlit’ing!
