prodigy v1.8 start the web app from Python for recipe textcat.manual

, ,

I used this code to run the app from python but it giving me errors:

prodigy.serve("textcat.manual",
"esg_tagged_test",
"en_core_web_lg",
"./ESG_classifications_analystA.jsonl",
None,
["ESG", "Not_ESG", "Confused"],
True,
None,
port=9000)

it's giving the following error:

\lib\site-packages\prodigy\recipes\textcat.py in manual(dataset, spacy_model, source, api, loader, label, exclusive, exclude)
127 log("RECIPE: Loaded model {}".format(spacy_model))
128 labels = label
--> 129 has_options = len(labels) > 1
130 log("RECIPE: Annotating with {} labels".format(len(labels)), labels)
131 stream = get_stream(

TypeError: object of type 'bool' has no len()

Can anyone tell me what's the correct syntax. I am using prodigy v'1.8.3'

Hi!

If I match the arguments to the textcat.manual method, it looks like you've forgotten the argument for api or for loader. Right now, True is being parsed as the argument for label (instead of your intended list) so this seems to be where the error comes from.

Does it work if you call

prodigy.serve("textcat.manual",
"esg_tagged_test",
"en_core_web_lg",
"./ESG_classifications_analystA.jsonl",
None,
None,
["ESG", "Not_ESG", "Confused"],
True,
None,
port=9000)

instead?

Thanks this worked.

@SofieVL. Recently my organization has upgraded to version 1.9.9. Can you please tell me the syntax for this version. I tried the below mentioned snippet but it didn't work.

prodigy.serve("textcat.manual",
"esg_tagged_test",
"./ESG_classifications_analystA.jsonl",
None,
None,
["ESG", "Not_ESG", "Confused"],
True,
None,
port=9000)

Hm, that looks correct to me at first sight, for 1.9.9. Could you paste the error you're getting?

here is the error

Thanks. Could you try again with

prodigy.serve("textcat.manual",
"esg_tagged_test",
"./ESG_classifications_analystA.jsonl",
None,
None,
None,
["ESG", "Not_ESG", "Confused"],
True,
None,
port=9000)

(i.e. one more None to fill the place for the deprecated variable _ in the function call)

@SofieVL Thanks it worked but with a bug. When I run the above lines of code, the app starts on the given port but with an error.

 Starting the web server at http://localhost:9002 ...
Open the app in your browser and start annotating!

I checked the port, no event was running on it prior to running the above script.

Hm, I'm not really sure what that last error means, especially if you say you checked the port.

Are you able to reboot and/or try again in a fresh environment? Perhaps you've ended up in some inconsistent state after upgrading?
