Thank you so much for the saving solution. Will it happen after every iteration or after 1 epoch?

I’m getting this message (using Windows) and I don’t know what is the problem:

$ snark start -t fast.ai --jupyter
Setting up the pod...
Connecting to the pod...
ssh: connect to host 173.209.172.209 port 10095: Connection timed out

Can you message me your username? I’ll take a look. You can also message us on our website chat box for support.

I am not sure. I believe after every epoch. There is a thread about it here

It is little tricky, I’m not sure that I will get to the end of epoch. I’ll dig in to see how to save after 100 or 1000 iterations.

With callbacks you can customize whatever behaviour you need. Look here: https://github.com/sgugger/Deep-Learning/blob/master/Using%20the%20callback%20system%20in%20fastai.ipynb

Guys, i been getting this error. Can you help me out?

snark start --pod_type fast.ai --jupyter
Setting up the pod…
Error: Couldn’t successfully schedule pod execution. Please try again

am on ubuntu 18.04 LTS

Removed {PATH}/tmp and it runs fine now.

Thanks for the service. But for some reason it is not working anymore for me:

$ snark start --pod_type fast.ai --jupyter

We really appreciate the interests from fast.ai community but we are bottlenecked on system scalability right now. Working hard on the upgrade. In the mean time the service may be a unstable. Will annouce here once we’re done with the upgrade.

check if you already have a pod: snark ls
If you do: snark attach pod_name
If you don’t: snark start --pod_type fast.ai
you can also snark start pod_name -L 8888:localhost:8888 --jupyter

Didn’t work for me :frowning:

Hi @snarkai,

I’m facing while running the notebook (ml course lesson 4), it says kernel error and when I click on that here’s what it shows.

OSError: [Errno 28] No space left on device

During handling of the above exception, another exception occurred:

Any suggestions what to do?

Thanks,

@SKS Working on system upgrade now. In the mean time the service may be a unstable. Will let you know once we’re done with the upgrade.

I thought i’m doing something wrong, thanks @snarkai

I just register, but the promo code (FastAI2018) was wrong, used or expired.

Promo code wrong, used or expired :sob:

Hi @snarkai , I get “Promo code expired error” when i tried with FastAI2018 code…
can you help me here?

@mengtanx sorry we’re out of quota for the promo code.

@karthiksuhas hey sorry but we run out quota for the promo code program
