Trainy Policy Nightly

0.1.0.dev20260430120117 verified Fri May 01 auth: no python

Nightly builds of Trainy's Skypilot policy package. Provides policy management for SkyPilot-based training workloads on cloud infrastructure. Current version is 0.1.0.dev, Python 3.9+ only, updated nightly.

pip install trainy-policy-nightly

Common errors

error ModuleNotFoundError: No module named 'trainy_policy_nightly' ↓

cause The package name includes hyphens, so the import path is not the same as the package name.

fix

Use 'from trainy import ...' instead of trying to import from 'trainy_policy_nightly'.

error ImportError: cannot import name 'Policy' from 'trainy' ↓

cause The installed version of trainy may be too old or the nightly package did not update the installed trainy correctly.

fix

Ensure you have installed the latest nightly: 'pip install --upgrade trainy-policy-nightly'. Also verify that only one version of trainy is installed.

error ValueError: AUTH_KEY environment variable not set ↓

cause The Policy object requires authentication key via environment variable AUTH_KEY.

fix

Set the environment variable before running: export AUTH_KEY='your-key-here'

Warnings

breaking This is a pre-release nightly version (0.1.0.dev). APIs are unstable and may change without notice. Do not use in production. ↓

fix Pin to a specific stable release once available, or use trainy (stable) instead.

gotcha The package name (trainy-policy-nightly) is not a Python import name. It installs the 'trainy' package which may already be present in your environment. Conflicts can occur if a different version of trainy is already installed. ↓

fix Install this package in a virtual environment to isolate from other versions of trainy.

deprecated Nightly builds may be replaced by stable releases. Check for a non-dev version of trainy-policy (or trainy) before relying on this package long-term. ↓

fix Monitor https://pypi.org/project/trainy-policy/ for stable releases.

Imports

Policy
wrong
```
from trainy_policy_nightly import Policy
```
correct
```
from trainy import Policy
```
This nightly package does not expose its own top-level module; import from the stable 'trainy' package.
load_policy
wrong
```
from trainy_policy_nightly import load_policy
```
correct
```
from trainy.policy import load_policy
```
Nightly builds add new features under the same namespaces as the stable package.

Quickstart

Basic usage: import Policy from trainy (not this nightly package) and authenticate via environment variable.

import os
from trainy import Policy

# Ensure AUTH_KEY is set
auth_key = os.environ.get('AUTH_KEY', '')
policy = Policy(auth_key=auth_key)
print(policy.list())
