Setup on Salamander

(Jesús Pérez) #4

Yes, but what I mean is that in the Salamander machine the packages from bcolz are not loaded. In my paperspace machine the fastai image run without this issue :slight_smile:

Yes - but this topic and discussion is for the new upcoming course, which uses fastai v1. @ashtonsix states above that he’s installed fastai v1. So please don’t use this topic for discussing the previous version of the course.

I really appreciate such a easy to understand UI and useful service!

I think the nvidia driver version here 296 is wrong, maybe typo?

Wow, sounds great, if you can make “AWS credits usable on Salamander”, I am already avid user of Salamander, but if you can add option to use AWS credit, then it will be fantastic…

@sashankpappu With Salamander, fastai 1.0 is available already (as “fastai”)

@jm0077 Salamander includes both fastai 1.0 & 0.7. You can run both old & new course material.

These are the available kernels:

kernel_1

After opening a notebook you can change your selected kernel with the selector in the top-right:

kernel_2

This thread is for supporting students using version 1.0, for any questions re fastai 0.7 please email support@salamander.ai or ask in the 0.7 support thread

@crcrpar nvidia-296 should be the version installed on Salamander, here’s the install script I used for the drivers:

sudo add-apt-repository -y ppa:graphics-drivers/ppa
sudo apt-get update
sudo aptitude install -yq nvidia-396
sudo apt-mark hold nvidia-396
sudo shutdown -r now

Hey @ashtonsix, just wanted to say thanks so much for your service. I’ve set up ML boxes on AWS, GCP, Paperspace, you name it, but this was hands down the easiest time I’ve had getting up and running with both PyTorch and Tensorflow with Tensorboard. I’ll definitely be recommending this to others…

@bartdegoede, @johnhartquist: thanks! It’s silly for students & scientists to repeat the same rituals thousands of times when it only takes one person to setup. I’m just amazed nobody from aws or gcp tried to make this stuff easier.

Is

K80 GPU

can you use fastai v1 with jupyter notebook as well? or does it only work with jupyter lab?

JupyterLab is just an IDE for working with notebooks, code and data. When you are using JupyterLab you would still be using your Jupyter notebooks in the usual way.

Thanks Andrew, just tested the jupyter notebook option but in the courses directory inside fastai there were 0.7 courses so switched to jupyter lab

opened jupyter lab
selected ‘fastai’ which i understand is v1
imporeted lesson 1 from new course
and got error message when importing fastai:

from fastai import *
from fastai.vision import *
import fastai.vision.transform as foo 

---------------------------------------------------------------------------
ModuleNotFoundError                       Traceback (most recent call last)
<ipython-input-2-bb50de15a0f6> in <module>()
      1 from fastai import *
----> 2 from fastai.vision import *
      3 import fastai.vision.transform as foo

ModuleNotFoundError: No module named 'fastai.vision'

am i doing something wrong here? thanks for your help!

@bluesky314 The K80 is a great option for the fastai course. You’ll probably want to ssh into your server to download data / weights (click “Setup Access Keys” & follow along)

@miwojc

both Jupyter Lab & Jupyter Notebook work well - they just look different is all. Jeremy will be teaching using Jupyter Notebook so if you’d like to use the same thing open “Preferences & Account Details”, then click “Switch to Jupyter Notebook”

If you selected the “fastai” kernel that should work fine. I’m updating the images today in preparation for Monday & will double-check the lesson1 notebook works. (if you can’t figure it out you may want to create a brand new Salamander server on Monday)

Thanks for a great service!
N00b question here: In the “Design Another Server” page it states “NB: Once launched, Salamander can’t install new software automatically”
How do I update fastai and pytorch to the latest version? I tried

conda update -c fastai fastai

And got

PackageNotInstalledError

I’m missing something here…

@Edward conda updates on Salamander have been broken for the last 3 days. I’m working on a fix right now.

Once fixed, you’ll need to run “source activate fastai” before “conda update fastai” (no channel needed for updates). I also recommend creating a brand new Salamander server on Monday.

@ashtonsix How do I buy credits? does it just keep on taking 20$ amounts from my account? Also what does “Setup access key” do and how do I SSH into my laptop as you said? (I’m totally new to this)

Is there a running timer I can see how much time server has been running?

In order to completely stop my server do I have to just log out or click ‘destroy’? How do I stop my server to halt the time usage but access it again later?
