Hello,
I am trying to run the sample code from “Instantiate multiple assets from a props folder” from your documentation .
and am getting this error:
OSError: [Errno 22] Invalid Argument

c:/users/ccc/appdata/local/ov/pkg/code-2022.1.1/kit/plugins/bindings-python\omni\kit\app\_init_.py(92): write

executing: rendomize_tet1.py...(20): <module>
I am on Windows, running Code 2021.1.1 Beta.
Nucleus is running.
Here is the dump from the log file:

Any help is welcome.
Can you post the exact code you are executing? I tried the example (copy paste directly in the script editor) and it works. Judgin by the error, the registering of the custom randomizer function seems to be the issue
I copy-pasted the example code as well:
import omni.replicator.core as rep
with rep.new_layer():
PROPS = 'omniverse://localhost/NVIDIA/Assets/Vegetation/Plant_Tropical/'
plane = rep.create.plane(scale=10, visible=True)
def get_props(size):
instances = rep.randomizer.instantiate(rep.utils.get_usd_files(PROPS, recursive=True), size=size, mode='point_instance')
with instances:
rep.modify.pose(
position=rep.distribution.uniform((-500, 0, -500), (500, 0, 500)),
rotation=rep.distribution.uniform((-90, -180, 0), (-90, 180, 0)),
)
return instances.node
rep.randomizer.register(get_props)
# Setup randomization
with rep.trigger.on_frame(num_frames=30):
rep.randomizer.get_props(3)
Further,
I get EXACTLY the same error when I run this custom code:
import omni.replicator.core as rep
with rep.new_layer():
render_product = rep.create.render_product('/World/Camera', (1024,1024))
def create_random():
bottle = rep.get.prims(path_pattern="/World/wine_bottle_1/default")
with bottle:
rep.modify.semantics([('class', 'wine_bottle')])
rep.modify.pose(rotation=rep.distribution.uniform((0, 0, 0), (0, 0, 360)),
position=rep.distribution.uniform( (-13.6, 84.6, -10.6), (79.6, 173.6, -10.6))
)
return bottle.node
rep.randomizer.register(create_random)
#writer = rep.WriterRegistry.get("BasicWriter")
#writer.initialize( output_dir="d:/datasets/omniverse/content/tests/", rgb=True, bounding_box_2d_tight=True)
#writer.attach([render_product])
with rep.trigger.on_frame(num_frames=200):
rep.randomizer.create_random()
NOTE: I am running this AFTER I manually create a scene.
Try closing code down, opening it again and run it in a new world. I had errors in the past, where I had to restart the program. Also make sure Nucleus is running with all services up
@simon.steinmann Restarting works! [facepalm]

I had the exact same issue in the past. If you are able to recreate the error, please post it. For me it was something along the lines:
Run a faulty script that throws an error
Run a correct script after and it throws errors too
Restart Code
Run correct script again, now it works
Maybe you can try some things and see if you can get a reproducible error.
