dl-cloud

Cloud Utilities for Deep Learning ⛅️

A super lightweight cloud management tool designed with deep learning applications in mind.

Built with the belief that managing cloud resources should be as easy as:

import cloud

cloud.connect()
train_my_network()
cloud.down()

We welcome all contributions, suggestions, and use-cases. Reach out to us over GitHub or at [e-mail] with ideas!

Quickstart

Install:

Sort of stable:

sudo pip install dl-cloud

Bleeding edge:

git clone [e-mail]:for-ai/cloud.git
sudo pip install -e cloud

Config:

See configs/cloud.toml-* for instructions on how to authenticate for each provider (Google Cloud, AWS EC2, and Azure).

Place your completed configuration file (named cloud.toml) in either root / or $HOME. Otherwise, provide a full path to the file in $CLOUD_CFG.

If you use GCP as a provider for your cloud.toml it will use GCP Instance metadata APIs to fetch APIs. If you want to configure for Google Cloud Build, please use;

is_gcb = true
zone = '{{DESIRED_ZONE}}' 

Usage:

GPU

import cloud
cloud.connect()

# gpu instances have a dedicated GPU so we don't need to worry
# about preemption or acquiring/releasing accelerators online.

while True:
  # train your model or w/e

cloud.down()  # stop the instance (does not delete instance)

TPU (Only on GCP)

import cloud
cloud.connect()

tpu = cloud.instance.tpu.get(preemptible=True)  # acquire an accelerator
while True:
  if not tpu.usable:
    tpu.delete(background=True)  # release the accelerator in the background
    tpu = cloud.instance.tpu.get(preemptible=True)  # acquire a new accelerator
  else:
    # train your model or w/e
    
cloud.down()  # release all resources, then stop the instance (does not delete instance)

Documentation

cloud.connect()

Takes/Creates a cloud.Instance object and sets cloud.instance to it.

returns	desc.
cloud_env	a cloud.Instance.

cloud.down()

Calls cloud.instance.down().

cloud.delete(confirm=True)

Calls cloud.instance.delete(confirm).

cloud.Resource

properties	desc.
name	str, name of the instance
usable	bool, whether this resource is usable
methods	desc.
up(background=False)	start an existing stopped resource
down(background=False)	stop the resource. Note: this should not necessarily delete this resource
delete(background=False)	delete this resource

cloud.Instance(Resource)

An object representing a cloud instance with a set of Resources that can be allocated/deallocated.

properties	desc.
resource_managers	list of ResourceManagers

Amazon EC2

cloud.AWSInstance(Instance)

A cloud.Instance object for AWS EC2 instances.

Azure

cloud.AzureInstance(Instance)
