Stage1 preprocess not working #6

Closed stefanknegt closed 4 years ago

stefanknegt commented 4 years ago

I am running into a problem with the preprocess script. I get the following error after updating the config file and renaming the data (where XYZ is a location on my machine). I have checked this exact path and it is correct. So it seems to be the case that the script cannot make the .h5 file, while this location is writeable. I also tried running it with sudo.

Do you have any idea what I am doing wrong? Thanks a lot!

I don't know. But perhaps it's because you don't have ffmpeg command installed on your machine, or perhaps python does not know where exactly to find it.

Looks like you're on Mac. I use Ubuntu (and so did the original author) so I don't know how to make sure python can execute ffmpeg, but you should check that.

As described in the readme, there's a branch "portable_submission'" which does not use ffmpeg.

The version on the portable_submission branch works fine, thanks!
