Error while converting pcd to depth image #19

Hi, I am getting this error while converting pcd to depth image using generate_cornell_depth.py.

OpenCV Error: Unsupported format or combination of formats (Only 8-bit 1-channel and 3-channel input/output images are supported) in cvInpaint, file /build/opencv-L2vuMj/opencv-3.2.0+dfsg/modules/photo/src/inpaint.cpp, line 751

Please help.

Hi, Inpainting of float-valued arrays is only supported in opencv version >=3.3.0. Looks like you have version 3.2. Try upgrading to a newer opencv version.

It works in opencv version 4.1.2. Thank you for the help.
