v0.0.33

Highlights

Docker dev & prod workflows

We released a new guide showing how you can use the same docker image on a Runhouse cluster for both local development and production.

Local Development: We now support passing in requirements to the Runhouse env object instead of preemptively sending the env to the function, ensuring that local changes are synced over.

dev_env = rh.env(name="dev_env", env_vars={"HF_TOKEN": "****"}, reqs=["diffusers", "transformers"])

# we pass in the env object to ensure any requirements specified in the env will be synced onto the cluster properly
dev_fn = rh.function(is_transformers_available).to(cluster, env=dev_env)

Production: The docker image holds all the packages and versions we want, ensuring reproducibility and reduce ingress costs of installing dependencies on each production cluster.

Improvements

• If no package version is specified, install the same version that is installed locally (#1058)
• Convert folder to a Module (#995)
• Support constructing an empty env with only a name (#1095)
• Support loading an on-demand cluster from name locally in addition to Den (#1093)
• Add option to skip loading resources from Den (#1096)
• Update client connection flow to reduce check server calls (#1098, #1141)
• Updating Folder APIs when interacting with a cluster (#1147, #1116, #1108)
• Add launched properties to ondemand cluster config (#1139)
• Stream logs in SSH setup commands (#1211)
• Logging updates and improvements (#1177, #1178, #1204)
• Update command running for Kubernetes, and support Docker images with Kubernetes clusters (#1173, #1174)

• Convert cluster rsync method to public (#1082)

Bug Fixes

• Remove callable param from Folder APIs (#1101)
• Fix folder construction in the Package (#1083)
• importlib support for Python 3.7 (#1073)

v0.0.32

Highlights

Changes to reqs, packages, and env installation

More explicit sycning behavior between local and remote development, and more flexible support for package installations on the cluster.

working_dir env argument
Previously, you could specify a "working directory" as part of your Runhouse env to sync over to a cluster. By default, this working directory is based on the folder that you are running your Runhouse Python code from (perhaps totally disconnected from the location of the coe you're sending over). This behavior changes in this release, and we now instead sync over the package in which the local class or function being sent to the cluster belongs. This eliminates unexpected sharp edges users encountered with working_dir setting, and we look to deprecate working_dir sometime soon (though this should not be disruptive). To specify folders to sync, one can directly pass local paths into the reqs of the Runhouse env.

env = rh.env(
            name="env_with_local_package",
            reqs=["pandas", "torch", "~/path/to/package"],
    )

Local path detection
When sending over a function or module that imports local code to a remote cluster, we now automatically detect [1] the package on the filesystem corresponding to that code, add it to the env requirements, and sync it over to the cluster.

Local package detection
You can now pass the name of a local Python package, whether installed from source or editably, and we'll detect the correct directory to sync over. This is important for teams collaborating on shapred repos, who may not have their clones saved in the same place.

Increased package installation support
Pip install will now work properly for local folders, in addition to package strings. Including a requirement that is installed locally will also sync appropriately to the cluster.

• Pip install method will correctly work for local folders as well (#998)
• Importing from a given file will now detect [1] a package on the filesystem to sync based on that file, add that to the envs reqs, and then sync it (#914)

Updated Connection Flow

Improvements to detecting and checking the HTTP server connection. Improved and faster approach to fallbacks and retries when unable to reach the client. As part of the connection refactor, ondemand clusters are no longer automatically brought up when there is a call made to/on it. Rather, one needs to manually call up() or up_if_not() to bring up the cluster if it is not already running.

Deprecations

Remove support and clean up docs for features that are no longer maintained. See release notes below for complete list.

BC-Breaking

Package & Envs

• Locate working dir in breath first approach (#908)
  • Search for local of module based on it's file location, rather than runhouse or current working directory
• Remove default working dir from \. to None (#915)
  • Working directory is no longer synced over by default when sending to a cluster. Instead, it can be specified by passing in the corresponding Package in the env reqs
• Selectively sync runhouse for default restart behavior (#1020)

Other

  • Previously, when making a call to or on an ondemand cluster that is not already running, Runhouse automatically brings up the cluster. This behavior changes in this release, and one will need to add run cluster.up() or cluster.up_if_not() to start the ondemand cluster.

Doc & Examples

• Add llama 3 fine tuning example (#939, #942)
• Update module API example (#950)
• Update architecture overview (#1036)
• Add up_if_not() in examples and tutorials (#999, #1009)

[1] The detection algorithm for what to sync when you have an importable function or module is as follows:

• Start with the file that contains this importable function or module on the filesystem
• Go up directories till you find any of the following config files ".git", "setup.py", "setup.cfg", "pyproject.toml", "requirements.txt"

v0.0.31

Quick release to allow passing Sky kwargs to ondemand_cluster (#978).

Highlights

[Alpha] On-demand Docker Clusters

This release adds support for using a base Docker image in conjunction with an on-demand cluster. By specifying the image_id field in the format docker:<registry>/<image>:<tag> in the cluster factory, the corresponding Docker container will be downloaded when the cluster is launched. The Runhouse server is then started inside the Docker container, ensuring that anything that goes through Runhouse will be run inside the container environment.

For more information on usage, such as setting up environment variables for using private Docker registries, please refer to the User Guide.

docker_cluster = rh.ondemand_cluster(
    name="pytorch_cluster",
    image_id="docker:nvcr.io/nvidia/pytorch:23.10-py3",
    instance_type="CPU:2+",
    provider="aws",
)

runhouse status: Improving visibility into cluster utilization and memory consumption

Improved Cluster Status

Runhouse now provides a more comprehensive view of the cluster's utilization and memory consumption, providing more coverage over the true utilization numbers across each worker and head node of a the cluster.

Information surfaced includes: PID, CPU utilization, memory consumption, and GPU utilization (where relevant).
This data can be viewed as part of the runhouse status CLI command:

v0.0.27

Highlights

Custom cluster default env support and lots of new examples!

Cluster Default Env

Runhouse cluster now supports a default_env argument to provide more flexibility and isolation for your Runhouse needs. When you set up a cluster with the default env, Runhouse first installs the env on the cluster (any package installations and setup commands), then starts the Runhouse server inside that env, whether it be a bare metal or even conda env. Future Runhouse calls on/to the cluster, such as cluster.run(cmd), rh.function(local_fn).to(cluster), and so one, will default to run on this default env. Simply pass in any runhouse Env object, including it's package requirements, setup commands, working dir, etc, to the cluster factory.

my_default_env = rh.env(
    name="my_default_env",
    reqs=["pytest", "numpy"],
    working_dir="./",
)
my_conda_env = rh.conda_env(name="conda_env1", env_vars={...})  # conda env

cluster = rh.cluster(
    name="my_cluster",
    instance_type="CPU:2+",
    default_env=my_default_env,   # or my_conda_env
)

cluster.run(["pip freeze | grep pytest"])  # runs on default_env

Improvements

• Introduce support for custom cluster default env (#678, #746, #760)
• Start our own Ray cluster instead of using SkyPilot's (#742)
• Exception handling for Module (#747)
• Disable timeout in AsyncClient (#773)
• Only sync rh config to ondemand cluster (#782)

Bug Fixes

• Set CPUs for ClusterServlet to 0 (#772)
  • previously, cluster servlet was taking up 1 cpu resource on the cluster. set this to zero instead
• Set den_auth default to None in cluster factory (#784)
  • non-None default argument causes the cluster to reconstruct from scratch (rather than reloaded from rns) if there's a non-None argument mismatch
