Using the DevBox
Accessing the DevBox
Connect to the DevBox by SSH over the internal network. It is on:
- 192.168.2.202
- Username: researcher
- Password hint: littleamount
It has a /bulk samba share that can be mounted from the RDP. Follow the instructions on Help:Access RDP Server.
Specification
Our DIGITS DevBox, affectionately named after Lois McMaster Bujold's fifth God, has a XEON e5-2620v3 processor, 256GB of DDR4 RAM, two GPUs - one Titan RTX and one Titan Xp - with room for two more, a 500GB SSD hard drive (mounting /), and an 8TB RAID5 array bcached with a 512GB m.2 drive (mounting the /bulk share, which is available over samba). It runs Ubuntu 18.04, CUDA 10.0, cuDNN 7.6.1, Anaconda3-2019.03, python 3.7, tensorflow 1.13, digits 6, and other useful machine learning tools/libraries.
Working in Tensorflow
After you've connected to the box as researcher, you should be in /home/researcher. If not, cd there. Then load the virtual environment:
source ./venv/bin/activate
Test tensorflow:
python -c "import tensorflow as tf; tf.enable_eager_execution(); print(tf.reduce_sum(tf.random_normal([1000, 1000])))"
Sample CNN Projects
There are some nice Tensorflow CNN tutorials online:
- https://www.tensorflow.org/tutorials/estimators/cnn
- https://www.tensorflow.org/alpha/tutorials/images/intro_to_cnns
- https://www.tensorflow.org/tutorials/images/deep_cnn
Some of which use standard datasets:
The code for MNIST.py is in E:\projects\tensorflow.
Word2Vec
There's a nice Word2Vec guide with code and data here: https://www.tensorflow.org/tutorials/representation/word2vec
DIGITS
DIGITS runs in docker containers. See https://docs.nvidia.com/deeplearning/digits/digits-release-notes/running-digits.html
As root run:
docker run --runtime=nvidia --name digits -d -p 5000:5000 nvidia/digits
Then browse to http://192.168.2.202:5000
Notes
Docker won't run if you left a container with the same name running (active or not). List docker containers:
docker ps -a
Stop a container:
docker stop containername
Prune them (-a is all, -f is no prompt)!
docker system prune -af
If you do a full prune, then docker will download a new image for nvidia/digits:latest
