RE: fastai.text

Not sure if I missed it.

Given that the base language model is Wiki103 and you use a domain specific language model that you train yourself.

If the domain language in the domain model is very different (technical terms etc.), do I add this vocab to the wiki103 one? I remember that Jeremy mentioned a limit of 60,000 words…

TypeError: split_from_df() got an unexpected keyword argument ‘cols’ while executing code for IMDB of lesson 3

data = (TextList.from_csv(path, ‘texts.csv’, col=‘text’)

            .split_from_df(cols=2)

            .label_from_df(cols=0)

            .databunch())

same hera

Is it normal that my GPU (gtx 1080 ti) is making like “tic tic tic” sound when I’m training model? It seems that it is making “tic” sound every time when percent is increasing.

Hi, Is lesson 4 not recorded fully? I’m only able to see 2hrs of content in Lesson 4 live link now.

There was a crash during the live recording, but as mentioned upthread, you can find the rest using these very helpful links: https://forums.fast.ai/t/lesson-4-links-to-different-parts-in-the-video/30338

It would be helpful if the course notebooks could have the top cell specify which version of fastai they were created with. I’m having a hard time getting the Planet notebook to work now, seeing this error:

ImageItemList is not defined

I am using fastai==1.0.22

I only see 1.0.22 in the official releases? https://github.com/fastai/fastai/releases

Thanks though … I’ll try with an upgrade!

Maybe , I was updated a bit to early and my dataset and dataloader creation for test set was broken with 1.0.24. I will figure out ho to handle it later today.
Something related to this thread https://forums.fast.ai/t/error-when-adding-in-a-test-set-via-add-test/30413

Using 1.0.24 worked for me. Thanks @ademyanchuk.

Next question. Is there an interpretation class for multi-label classification? What’s the right way for us to do similar analyses here?

I would like to see confusion matrix, top losses, etc for my multi-label classification of pizza toppings, but the single image classification interp object doesn’t seem to be working for this.

I didn’t dig deep in that case. So, have nothing to say, sorry)

Even more helpful would have been to stick with a single version for a course, IMHO.
