"ERROR: `input_path` is not a directory"

[rockywind]

Describe the bug When I run the script in my own dataset, I met the error below! The script is that below. ns-process-data images --data /DATA2/xiaoquan.wang/nerfstudio/data/own_data/pic_tmp/img/ --output_dir /DATA2/xiaoquan.wang/nerfstudio/data/own_data/pic_tmp/ Screenshots

Does /DATA2/xiaoquan.wang/nerfstudio/data/own_data/pic_tmp/ exist and what files are in there?

Hi, This is the data folder.

Hi, I modified these two codes so that they can run on the server.

new_data_0.zip This is my image file. I got same error.

I have also encountered this problem, this is because the number of images you provided is not enough to predict the camera poses. Take more photos or record a video instead

It may also be because your png/jpg are not the correct pixel format. For instance, I used ffmpeg to subsample a video and split it into 5 separate groups (couldn't use ns-process-data video for this), but the default ffmpeg datatype is yuv420p I think. COLMAP / OPEN CV cannot read this pixel data type.

Anyway, when I changed this command:

ffmpeg -i ${1} "${outdir}/frames/%03d.png"

to this one:

ffmpeg -i ${1} -pix_fmt bgr8 "${outdir}/frames/%03d.png"

Then COLMAP worked.

Hope this can help other ppl as well!
