Lesson 1 In-Class Discussion ✅

It looks like the link to ‘Amazon Web Services EC2’ on the http://course-v3.fast.ai/ website is broken. It links to http://course-v3.fast.ai/start_dlami.html not http://course-v3.fast.ai/start_aws.html .

@jeremy @rachel what’s the difference in installing pytorch and pytorch nightly? is it a cpu - gpu difference?
Any ideas on how i can use windows to use this setup of fast ai v1?

pisymbol · October 23, 2018, 1:41am

That might be a bit dangerous. Not sure how stable master is on a daily basis since its in active development. Caveat emptor.

sgugger · October 23, 2018, 1:42am

Windows isn’t supported by pytorch v1 yet, therefore it’s not supported by fastai v1 yet.

bluesky314 · October 23, 2018, 1:42am

No documentation when I search “ImageDataBunch” on the fastai.docs. How to read more about this?

Mauro · October 23, 2018, 1:42am

Why doesn’t everyone just use Google Colab instead of Paperspace, Amazon. etc. Colab is free .

rachel · October 23, 2018, 1:42am

Please don’t ask installation questions now. Jeremy will be explaining how to install and set up as part of the class.

_venkat · October 23, 2018, 1:43am

Hasn’t PyTorch supported Windows since v0.4?

nikhil.ikhar · October 23, 2018, 1:43am

Nigthly build (code) are deployed every day/night. They are tested/fixed every day. They can be unstable. I would say follow the recommended installation method initially.

pavan_alluri · October 23, 2018, 1:43am

thank you @sgugger
Any thoughts on the difference between pytorch & its nightly version?

stas · October 23, 2018, 1:44am

Not for all of us, it doesn’t work for me, see:

pisymbol · October 23, 2018, 1:45am

Exactly what it sounds like. pytorch (stable) pytorch nightly (latest/greatest/bleeding edge)

prsahu · October 23, 2018, 1:45am

Youtube stream is not working for anyone else?

stas · October 23, 2018, 1:45am

It’s supported, but they have no binary builds yet. You can build from source. there are success threads in the forums.

sgugger · October 23, 2018, 1:46am

Colab doesn’t support pytorch v1 yet, therefore it doesn’t support fastai v1 yet.

The latest version (the preview of version 1) doesn’t support windows (or MacOS on GPU) yet.

davidpfahler · October 23, 2018, 1:46am

Working well for me.

davidpfahler · October 23, 2018, 1:47am

~~I am running the notebook on colab right now, so not sure what the lack of support is, but I haven’t bumped into it, yet.~~

Colab does not appear to work with pytorchv1/fastaiv1

sgugger · October 23, 2018, 1:48am

Yet we have a mouthful of issues and errors thread in the forum
You can make it work somehow, but it’s not fully supported.

Galactrion · October 23, 2018, 1:48am

You are bound to run into dependency issues soon. I tested with colab unsuccessfully.
