Process cloud project through Python

[DocPopi]

Hello again 

I have another problem concerning the processing of a project on the Cloud. Here is my script:

Code: [Select]

import Metashape
from os import path, listdir


def import_images(chunk):
    img_folder = path.join(My, Path, Joined)
    img_list = listdir(img_folder)
   
    for i in img_list:
        new_path = path.join(img_folder, i)
        print(new_path)
        chunk.addPhotos([new_path])

def build_task_list(tasks):
    '''Match photos'''
    task = Metashape.Tasks.MatchPhotos()
    task.downscale = 0
    task.keypoint_limit = 40000
    task.tiepoint_limit = 4000
    task.generic_preselection = True
    task.reference_preselection = True

    # '''Compile the match photos task'''
    # n_task = Metashape.NetworkTask()
    # n_task.name = task.name
    # n_task.params = task.encode()
    # n_task.frames.append((chunk.key, 0))
    # tasks.append(n_task)

    tasks.append(task)


    return tasks


def main():

    output_path = path.join(Another, Path, Joined)
    tasks = []
    doc = Metashape.Document()
    doc.save(output_path)
    chunk = doc.addChunk()
    import_images(chunk)
    tasks = build_task_list(tasks)
    doc.save()

 
    client = Metashape.CloudClient()
    client.username = **********
    client.password = ************

    client.processProject(doc,tasks)



main()

The problem is that once the code gets to the "client.processProject' part, I get an error saying that a "Task object is expected".

I found another post on this forum with a similar problem (https://www.agisoft.com/forum/index.php?topic=13259.msg58833#msg58833) but there was no answer. I also tried to follow https://www.agisoft.com/forum/index.php?topic=10734.0, but here I get an error saying that the Method is not allowed. Of course, I have also been combing the user reference manual, but I haven't found anything that could help me further.

Thank you in advance for your help

Hello Popi,

Actually, you need to pass the list of NetworkTask objects to client.processProject.

Easy way to transform Task to NetworkTask is shown in lines 110-115 of the following script example:

Hi Alexey,

Thank you for your answer. I tried but I now have the "Method not allowed (405) " error. Here is what I wrote:

Code: [Select]

def build_task_list(tasks, doc, chunk):
    '''Match photos'''
    network_tasks = []
    task = Metashape.Tasks.MatchPhotos()
    task.downscale = 0
    task.keypoint_limit = 40000
    task.tiepoint_limit = 4000
    task.generic_preselection = True
    task.reference_preselection = True
    tasks.append(task)

    for t in tasks:
        if t.target == Metashape.Tasks.DocumentTarget:
            network_tasks.append(t.toNetworkTask(doc))
        else:
            network_tasks.append(t.toNetworkTask(chunk))

    return network_tasks


def main():

    output_path = path.join(My, Super, Path)

    tasks = []
    doc = Metashape.Document()
    doc.save(output_path)
    chunk = doc.addChunk()
    import_images(chunk)
    network_tasks = build_task_list(tasks, doc, chunk)
    doc.save()

     # Go retrieve the projects on the cloud
    client = Metashape.CloudClient()
    client.username = ****************
    client.password = ********************
   
    client.processProject(doc,network_tasks)



main()
But now the error says
"Exception : Error transferring https://api.agisoft.com:8086/v1.4/projects//processes - server replied: Method Not Allowed (status code: 405)".

What did I do wrong? I admit I'm not sure to understand the code you sent me, so maybe I didn't adapt it enough to my case.

Thank you again,

Popi

Sorry, I'm taking the liberty of upping this topic, because I still couldn't find the solution ^^

Hello Popi,

What Metashape version and build number you are using? I have tried to replicate the issue using your code, but it successfully starts the processing in the Cloud.

[DocPopi]

Hello Alexey,

Thank you for your answer. I'm using Metashape Professional 1.8.4, build 14671(64bit).

Am I using the right version?

Hello Popi,

You should upload the project to the cloud first: client.uploadProject(doc) and then call client.processProject()

Hey Alexey,

God I feel stupid, I had actually commented that line, but it was there all the time It works now, thank you so much!

Best,

Popi
