How do you use cv2 on Spyder?

To use OpenCV fully with Anaconda (and Spyder IDE), we need to:

  1. Download the OpenCV package from the official OpenCV site.
  2. Copy and paste the cv2.
  3. Set user environmental variables (so that Anaconda knows where to find the FFMPEG utility).
  4. Do some testing to confirm OpenCV and FFMPEG are now working.

Can cv2 read JPEG?

Typically, the cv2. imread function will return None if the path to the input image is invalid, so be sure to double-check and triple-check your input image paths! The function will also fail for unsupported image file types, although OpenCV can read a wide variety of them, including JPEG, PNG, TIFF, and GIF.

Can OpenCV read TIFF?

So, OpenCV can always read JPEGs, PNGs, and TIFFs.
