Error importing cv2

Does file uploader even work with streamlit share? Where do my uploaded files go?

Yes, I assure you that file_uploader works on Streamlit sharing.

Files don’t “go anywhere” per se, they stay in RAM in a BytesIO buffer. To use the uploaded file, you can pass this buffer (in your code, back and over) to whatever function needs to read the bytes. However, note that not all packages accept buffers. If your function happens to be one of them, then you need to save the buffer to an actual file.

How to access uploaded video in streamlit by open cv?

Seems wasteful, but if OpenCV really requires a file, I wonder if this will be acceptable: import streamlit as st import cv2 as cv import tempfile f = st.file_uploader("Upload file") tfile = tempfile.NamedTemporaryFile(delete=False) tfile.write(f.read()) vf = cv.VideoCapture(tfile.name)

Best,
