Hi José, 

The problem could be related to the file path: “C:/Users/José Ignacio/AppData/Local/Temp/pix4d.P1XkOA/model.lightgbm”.

The problem could come from “_José Ignacio” _in the file path. Could you please try to create another project using a different path that does not contain folders having special characters or spaces? I would expect the classification to work this way.

Please post an update if you try. Thanks!

Hi Pierangelo,

After several trials, I have realized the problem was my windows username. I had to uninstall and re-install the app again under a new windows user without any special character.

Now it works properly!!

Thanks for your prompt support

Great to hear that it is working! Your tests seem to confirm that the issue was with special characters in the installation path, in this case with the Windows user name that had a “space” and “é” in it.

Hi,

Dig of the year here, resurrecting a topic from 2018 at the end of 2023, but unfortunately this bad programming code is still there.

Space and special chars are valid on paths of both file system and registry since ever, and they should never be a problem for any well designed app.

I’m trying Pix4Dmapper now and this leaves me quite angry, honestly, as you can imagine.

The path to my home dir on my workstation was created by windows itself from my company’s office 365 email address, where my profile has my name “João Prates”, including naturally the characters " " and the “ã”.

Uninstalling the operating system and all the software installed is obviously not a solution nor workaround.

Please fix this.

Cheers,
