Lesson 2: Practical Deep Learning for Coders 2022

[@Karen-ls7hv]

thank you for making AI education free and accessible 😊

[@howardjeremyp]

It's my pleasure

[@nimbus1r]

❤ This course will have a ripple effect for an entire generation of programming

[@chuhaoliu5050]

Update for 2023. In Gradio deployment notebook, `intf.launch(inline=False)` needs to change to `intf.launch(inline=False,share=True)` to have the public web link.

[@cullenharris1837]

Where can we find the notebook at 41:32 for Dogs v Cats on your local?

[@hawperify]

Also wondering this, having trouble following along that this section...

[@paulmest]

It was covered in Lesson 1. Check out the Resources section here: course.fast.ai/Lessons/lesson1.html

[@bampy81]

Got the same problem. It's the app.ipynb file that I can't find. Did you manage to find it?

Thank you, Jeremy, and everyone involved in creating this great course. It only gets better with every new iteration!

[@strikingpotato3572]

Just like a Neural Network no? :)

[@prof.ravindravyas3035]

Dear Sir, Great Lecture and superb knowlege sharing session..............One thing I would like to quote is in start of lecture when speaker says " I am super excting to teach this lecture" .........students like me and others feel standing on race line and start running..........most enthusiastic teacher...........

[@mikementele]

I've taken many ML courses over the years and I love the hands on nature of this with Jupyter notebooks, the extra background provided with the book, the quizzes, and the top down approach that orients you on breadth before depth. This is done right from a pedagogy standpoint.

[@cojocarucosmin202]

Respect for giving out high quality information, you are the real deal and so few people actually know...

[@arkadymarchenko1516]

Hi Jeremy, I love the education your giving through your videos and non-coding parts of your book but I often find you notebooks are pretty buggy and down work out of the box. The last notebook provided for lesson 1 (is it a bird) required me to import another image crawler to make it work. For this lesson, the ddg image search wasnt working properly as well and I had to make major modifications. I love everything you're doing but I would love if you updated this course to provided updated and working notebooks to make it seamless for people like me to learn deep learning

[@palahnuk1]

Jeremy ... you are the real deal ... thanks for giving your personal time and energy to open the world of ML to mere mortals like us older engineers ... you are a real world blessing!

[@piecucci]

10:57 I was getting an error after running dls = bears.dataloaders(path) from the cells further fown in the notebook. I needed to change the quotations marks in the cell with bear_types for the variable path = Path("bears") (double quotation marks)... Took me some googling around to make it work!

[@piecucci]

I've also needed deindent the for loop for the bear_types and remove the folders created before running the code again. if not path.exists(): path.mkdir() for o in bear_types: dest = (path/o) dest.mkdir(exist_ok=True) download_images(dest, urls=search_images_ddg(f'{o} bear photo'))

[@frankkranktrangtmohammedny807]

​@@piecucci I had the exact same problem. Thanks for commenting this!🙏

[@zzznavarrete]

Also, whoever is using Gradio's version 4.39 or above, the following is code is for the Gradio interface: # creating the gradio interface image = gr.Image(height=192, width=192) label = gr.Label() examples:list = ['./assets/dog.png', './assets/cat.png', './assets/dunno.png'] intf = gr.Interface(fn=classify_image, inputs=image, outputs=label, examples=examples) intf.launch(inline=False)

[@TudiIveelt]

thanks!

[@lucianomarchezan2372]

thank you!!

[@DeepakKumarDataScience]

What is the repo used for this set of jupyter notebooks? The Fastbook directory seems to have the textbook version that uses Azure SDK keys whereas Jeremy refers to the DDG alternative. I am not able to find the right folder under the fast ai repos.

[@miskaknapek]

Thanks for this video too! I very much appreciate the content and the enthusiastic pedagogical style

[@rahmanoff]

Thanks Jeremy! p.s. if you try to go step by step and got error "module 'gradio' has no attribute 'inputs'", try gradio==3.48. It works well for me.

[@elvryn_]

So fun hearing anecdotes of classifying images of a dog cat with your daughter

[@dmoneyballa]

Thank you so much for adding the commands for wsl to add the drivers on ubuntu. this is the most time consuming part for me when I setup a new computer. I really appreciate it.

[@datalifenyc]

49:12 Looking at the source code for nbdev.export, there is no `notebook2script` function. The closest in functionality appears to be `nb_export(nbname, lib_path = None)`. nbdev version: 2.0.6. Did anyone run into the same issue?

[@datalifenyc]

This video is probably referencing v1 of nbdev. For v2, you can use: # Bash Terminal nbdev_export --path "app.ipynb" or # Jupyter Notebook from nbdev import nbdev_export nbdev_export("app.ipynb") A `nbdev` folder is created with the `app.py` file in it.

[@dingding4898]

anything to convert an existing project to nbdev?

[@JeffJohnston-l8x]

Where do I find the "Dog v Cats" Notebook shown at 41:27?

[@chuhaoliu5050]

It's way more fun to learn by building something people can actually use!! Thanks a ton!

[@AiEdgar]

No fillers so much knowledge I wish all my teachers were this good.

[@marktomm1959]

With gradio==4.28.3 the example code in the video won't work. error "module 'gradio' has no attribute 'inputs'" Fix: image = gr.Image(height=192, width = 192) label = gr.Label()

[@bhanutadepalli]

56:57 curl doesnt have --no-progress-meter option. If you are setting up on mac remove that option from the command

[@hiankun]

"And when I say one day, more specifically... today!" XD Today is a good day. 😀

[@KiLVaiDeN]

This is very neat content, and your way of explaining those concepts is calm and posed, very enjoyable to watch ! Thank you.

[@aworden]

Where can we get the locally run notebook that you used to create the python script for the gradio app? Could this be run in Kaggle instead of locally and exported / downloaded? It makes it confusing that you're jumping from Kaggle to colab to local notebooks. Is that necessary?

[@kophaihoang]

The weird dog at 47:20 is "Chó Dúi" and he is from Vietnam, it is unlucky that he just passed away last year :(

[@AnibalCarpio]

Where can I look for the notebook to lesson 2 using ddg method?, cause on the fastai book website still show the version using key and Microsoft Azure

[@ChrisLonsberry]

OMG, I'm so excited to see new updates to this course! EDIT: Is there somewhere that I can read about what has changed?

[@ishitaraj7723]

where is the notebook at 41:27 coming from?

[@enigmeta]

It seems that nbdev 2.0 works very differently, because the export doesn't work anymore. Is there a good tutorial on how to use the new version?

[@jasonholtkamp8462]

You know what's hilarious is that I actually read the book chapter before watching the lesson and I had the hardest time finding my Azure Bing API Key after I made my account and whatnot... It literally took me longer to just do that step than the entire rest of the lesson lol. And then Jeremy just goes yeah screw that I'm going to use duckduckgo instead haha.

[@zzznavarrete]

for those who are using windows and got the following error message: "NotImplementedError: cannot instantiate 'PosixPath' on your system", the fix is: import pathlib temp = pathlib.PosixPath pathlib.PosixPath = pathlib.WindowsPath

[@mamotivated]

@jeremy in the randomization/augmentation process in real-time in memory, does a single image and its variants all get included in a single batch? If they do, how does this affect the quality of the weight updates vs spreading some of the augemented images to other batches

[@33gbm]

Nice course. But you are always changing the references in the video, it would be nice to find the ipy notebooks you are working on in a single place.

6:57 Need to import widgets before using ImageClassifierCleaner from fastai.vision.widgets import *

I need triple the time of the video to understand it, but I am getting there, thanks! By the way, the dog-cat thing apparently is a puppy...

[@shubh9207]

Hello, is it fine to run Jupyter notebook on VS code instead of running it on a local browser?

[@jonathangrant7788]

You mention that the learner needs all the same functions it had in training. Is this due to using pickle? Can you just use cloudpickle instead and not provide the training environment?

[@miladrahimi3283]

This tutorials is really helpful, thanks so much. you are boosting my knowledge.

[@sayan7s]

Jeremy thank you so much for all the effort. It means a lot ! Really appreciate

[@jimshtepa5423]

what does calling 'train' method on dls object do? does it show the images that are used to train the model? what does 'valid' method do?

[@mehnaazmohiuddin]

In the step of cleaning the data . Are we moving the files in the folder ? Do we have to have to create the model again?

[@ericflynn5799]

I'm running into an issue where the ImageClassifierCleaner is not working properly in a Kaggle notebook. Anyone else face a similar issue and know a solution?

[@MyselfTheodore]

Re-running all the cells from the start fixed it for me

[@toromanow]

It says fastpages is deprecated and one should use quattro instead. Thoughts?

[@КсенияПак-ш6в]

Yes it can - don't despair!

[@mikementele]

This course is amazing

[@jordankuzmanovik5297]

Hi jeremy, as always great course. But what about practical deep learning from the foundation? I am waiting 2 years for those. Thanks

[@neild7457]

Thank you very much for this course :)

[@slf188]

Great lecture! Jeremy is amazing at explaining such cryptic concepts

[@mistercakes]

thank you for the great content. do you recommend jupyter notebook over jupyter lab? (any reason, is nbdev supported in jupyter lab?) also you mention number of epochs recommended. it could be useful just to give a number on how many epochs were needed to do the original training on the model that we are fine tuning against to give some perspective.

[@ashish31416]

Thank you for the amazing course.

[@gblazerify]

Great educational video!

I created a hugging space faces page and created a new space called "minimal", selected apachie, radio, and public. Im on mac and copied the repo into the terminal. I then tried to do code . but it says "command not found: code" I am not sure what I did wrong.

[@ladyblack679]

I had the same issue First make sure you have downloaded Visual Studio Code Open Visual Studio Code Type Cmd+Shift+P and input '> shell command' and click Shell Command: Install 'code' command in PATH command. Restart your terminal In the terminal type in “cd minimal” Then input “code . "

uninstall and reinstall vscode. Sometimes the environment path get corrupted and the updates don't happen properly

btw that dog cat image is actually a puppy that looks like a cat

[@derekcarday]

Is there a reason why you use windows? I've been working industry as a developer for 7 years now and have only seen one person use windows and they always had issues. Just curious if it's cuz microsoft now ships with linux kernel or if there's any benefits for deep learning.

[@howardjeremyp]

I like being able to use a stylus directly on the screen. I use WSL (Linux) or SSH into a Linux server for nearly all my work though.

[@priyanshutiwary9500]

how to study this course. does it only have 8 lectures ?

[@howardjeremyp]

No there's 25 lectures. Go to course.fast.ai/ .

[@davisisibor3509]

Watching this last few sections of this video as a frontend developer . Was one of my best moments 😂😂😂😂. I skipped the entire thing 😂😂😂😂😂

[@mansamusa559]

Love the course !! But I really recommend streamlit instead of gradio.. :D

so amazing classss

this is bery good thank you ;)

The dunno worked on my computer. it said 60% cat and 40% dog. it was just brilliant

[@juanmontero883]

Thank you so much!

[@NotaUserIam]

Love the course but I do hate the way you code. I have spent way too much time figuring out which imports are giving me which function I’m using

[@howardjeremyp]

To find out what import provides a function, type the function name and hit shift-enter.

[@JoshGodwinArt]

The one thing that didn't seem super clear to me is why he is doing everything in a Linux environment in the first place. Why not just install python and all the libraries on regular windows without that extra step of having to go to linux first.

[@bloody_albatross]

That dog-cat has an AI generated feel to me.

Thank you Jeremy, but we are programmers... 80% of time you spent on showing stuff we already know... git, jupiter etc... can you make 30 minute course with core concepts of fastai framework. What models when used etc...
