Nope. Maybe @radek ??
I have ordinary PC box, not a headless. But make notes on your struggle, would be great blogpost.

Have not experienced any issues - went for EVGA FTW3 because of its cooling.

Different GPUs will have different heat characteristics - for instance, a ZOTAC mini will nearly instantly heat up to ~90C.

I would not worry too much about fan control, etc unless you are seeing genuine issues (restarts, etc)

Issueas are the main reason I worry about fan control and I think that fan doesn’t work on max speed when it should :frowning:

maybe this article will help you:


you have access to nvidia-smi? It should show you GPU-fan usage

I’ve already read this blog post (just minutes ago) :slight_smile: I’ll try that scripts this evening. Thx for help. Wish me luck…

You can get GCP with regular card (debit card) no credit card required. I’ve got up to watch the lecture and was half-awake most of the time, eeh.

When I run learn.unfreeze() it unfeezes all the layers from what I understand, but it doesn’t learn from scratch just adjusts the existing weights? Because when I do unfreeze, learn, save, weights and load them and then run the sequence again I have different error rate.

this is what i understand too. that is unfreezing doesn’t ā€˜reset’ pretrained weights (for this there is pretrained=False argument).
when you load weights and run more epochs, the error decreases? i think it should unless it overfits?

Yes it decreases, I think I will experiment more on dataset that is processed faster (I did that on quick draw, using Radek tutorial, thanks for that Radek).

was good meetup! thanks for joining today! however there was a huge echo on my side i could barely hear you today. i hope next week will be better!

if someone is training of colab there is a easy way to use own dataset, if it is on Google Drive.

I saw you asking about situation, where there are not only cats/dogs (example) but also not-cats-dogs, other category.

Here is example:
They added additional category ā€˜background’ and made it 5 times bigger then other categories.
ā€œThe backgrounds should be as diverse a set as possible.ā€

If someone wants to get into Reinforcement Learning (I do :smiley:) , OpenAI just launched https://spinningup.openai.com/ . It looks like a great resource.

nice. thanks @sayko !

jeremy just tweeted yesterday that someone beat fastai team’s DAWNBench CIFAR10 training record by factor of 2.5x, interesting read:
