RunScript NetworkTask how to?

[smihic]

Hi,
  we are working on networking and we want to run Python scripts on network. Can you please provide an example how to perform RunScript task from Python, and how to access PhotoScan data from that script?

Best regards,
Srdjan

Hello Srdjan,

here's the script that starts another python script as a network task:

Code: [Select]

import PhotoScan

client = PhotoScan.NetworkClient()

task1 = PhotoScan.NetworkTask()
task1.name = 'RunScript'
task1.params['path'] = "processing/script.py" #path to the script to be executed
task1.params['args'] = "argument1 argument2" #string of the arguments with space as separator

path = "processing/project.psx"
client.connect('192.168.0.2') #server ip
batch_id = client.createBatch(path, [task1])
client.resumeBatch(batch_id)
print("Job started...")

and here's the script.py that should be executed as a network task (just a simple example):

Code: [Select]

import PhotoScan, sys

args = sys.argv
label = args[1] #the very first argument is the script path

doc = PhotoScan.app.document
chunk = doc.chunk
chunk.label = label

Hi,
  unfortunately, script called by RunScript task results in error. It seems that PhotoScan.app.document is None no matter which psx file it is called on. Can you please check?

Best regards,
Srdjan

Hello Srdjan,

It seems to be an issue in the version 1.2.4 build 2399 that will be fixed in the next update. Actually I was testing the script on the internal version where it has been already fixed. Sorry for the inconvenience.

Okay, can you tell me when we can except this new version? and are there workarounds in current version?

[Alexey Pasumansky]

I think we'll release the new version this month. As a workaround you can pass full path to the document among the script arguments and open the document in the working script via doc.open(), however, the path should be absolute and this workaround may fail if there are multiple processing nodes that see the script file under different absolute paths (for example, if there's a mixture of OS).

Thank you Alexey. Regarding the workaround, is there a way to for RunScript network task to work on multichunk project so that it will be executed on every chunk (script code is called for each chunk (like for standard functions))?

Hello Srdjan,

Having access to the active document should allow you to perform some custom operations for any or every chunk in this document.
