Unable to reproduce example about transformersum

The fix to solve this problem is now in the documentation.

Thanks, it does work perfectly!

Hi. It seems like my latest changes to the documentation did not build correctly so the information about this issue was not visible. To solve this issue please see this page, which will be on the ReadTheDocs documentation very soon. Essentially, set strict=False like so: model = ExtractiveSummarizer.load_from_checkpoint("distilroberta-base-ext-sum.ckpt", strict=False) and that should solve it.

Hi @HHousen! Thanks for your quick reply.
Now the model loads fine.

However, when I try to summarize a string, using

from extractive import ExtractiveSummarizer
model = ExtractiveSummarizer.load_from_checkpoint("my/path", strict=False) #ok
source = "This is just a try. Let's see if it works"
summary = model.predict(source)

I get:

C:\Users\silvia\Anaconda3\envs\TransformerSum\lib\site-packages\pytorch_lightning\core\saving.py:205: UserWarning: Found keys that are in the model state dict but not in the checkpoint: ['word_embedding_model.embeddings.position_ids']

ValueError: [E966] nlp.add_pipe now takes the string name of the registered component factory, not a callable component. Expected string, but got <spacy.pipeline.sentencizer.Sentencizer object at 0x000001B26E43A240> (name: 'None').

• If you created your component with nlp.create_pipe('name'): remove nlp.create_pipe and call nlp.add_pipe('name') instead.

• If you passed in a component like TextCategorizer(): call nlp.add_pipe with the string name instead, e.g. nlp.add_pipe('textcat').

• If you're using a custom component: Add the decorator @Language.component (for function components) or @Language.factory (for class components / factories) to your custom component and assign it a name, e.g. @Language.component('your_name'). You can then run nlp.add_pipe('your_name') to add it to the pipeline.

Process finished with exit code 1

Try opening the extractive.py file and changing line 1177 from nlp.add_pipe(sentencizer) to nlp.add_pipe("sentencizer"). Then, delete the previous line (line 1176). If this works I will merge this change to the master branch.
