Proper method to close project via python API

[ashalota]

I've noticed I end up with a 'read-only' lock on my projects some times after I have made adjustments through my python script.

What is the correct way to close the document so it goes away when I am done working on it in python? I don't see a "close" method anywhere in the API. My best guess is to just open a blank Metashape project when I am done with my current project?

Hello ashalota,

Can you please describe the common workflow that you are using, when the "read-only" lock appears? Do you perform multiple operations with the projects using scripting in the same Metashape instance?

I believe I may have solved this issue by running "Metashape.Document()" when I am done with my process.

The issue occurred because I had been opening a project, working on it, and then transferring it to another computer. The other computer then never received any information that I ultimately closed the project. I am now making sure to "close" the project within my script by running Metashape.Document() before sending it to the other computer.

Same here. After every time I ran my code, I would open the new project and it would be as read-only, which caused Metashape to be unstable!
I was looking for a close method for the document in my code, something like doc.close() but didn't find it in the API manual.

There is doc.open(project_name), and doc.save(), why not doc.close()?

Your solution of Metashape.Document(), does solve the problem. It enables me to open the project right after the code ran. I just don't know if that is what Agisoft expected us to do, or is there a more elegant way.
thanks

Hello,
Almost two years ago, it seemed like I had a bandaid to closing a Metahsape project processed completely with Python API.
The last two code lines are:

Code: [Select]

Doc.save()
Metashape.Document()Yet,
1. If I open with the GUI I  get a message
             The project is opened in read-only mode because it is already in use by DESKTOP.... or was not closed
             properly. Do you want to edit it anyway?
2. If I open the existing project with python API I cannot save the changes

Code: [Select]

OSError: Document.save(): editing is disabled in read-only mode
So what am I doing wrong at the end of my python code after finishing processing?

Hello,

same problem here!
I´m still using  V1.84
I´ve tried both version (also together  )
 

Code: [Select]

doc.save(path = '...psx'))
#Metashape.app.quit()
quit()

I found a way to fix it manually by deleting the lock file in the .files subfolder - but we are using Metashape with several licenses in different locations, so I won´t tell them please delete it or write a little batch to do this.

Thanks Marius, that is a creative solution!

Metashape team, or anyone else, is there no proper way to close to the project so it can be opened later to read and write?
Thanks
