Humanloop Python Library

The Humanloop Python library provides convenient access to the Humanloop API from Python.

Installation

pip install humanloop

Usage

Instantiate and use the client with the following:

from humanloop.client import Humanloop

client = Humanloop(
    api_key="YOUR_API_KEY",
)
client.prompts.upsert(
    model="model",
)

Async Client

The SDK also exports an async client so that you can make non-blocking calls to our API.

from humanloop.client import AsyncHumanloop

client = AsyncHumanloop(
    api_key="YOUR_API_KEY",
)
await client.prompts.upsert(
    model="model",
)

Exception Handling

All errors thrown by the SDK will be subclasses of ApiError.

import humanloop

try:
    client.prompts.call(...)
except humanloop.core.ApiError as e: # Handle all errors
  print(e.status_code)
  print(e.body)

Advanced

Timeouts

By default, requests time out after 60 seconds. You can configure this with a timeout option at the client or request level.

from humanloop.client import Humanloop

client = Humanloop(
    ...,
    # All timeouts are 20 seconds
    timeout=20.0,
)

# Override timeout for a specific method
client.prompts.call(..., {
    timeout_in_seconds=20.0
})

Retries

The SDK is instrumented with automatic retries with exponential backoff. A request will be retried as long as the request is deemed retriable and the number of retry attempts has not grown larger than the configured retry limit (default: 2).

A request is deemed retriable when any of the following HTTP status codes is returned:

• 408 (Timeout)
• 429 (Too Many Requests)
• 5XX (Internal Server Errors)

Use the max_retries request option to configure this behavior.

client.prompts.call(..., {
     max_retries=1
})

Custom HTTP client

You can override the httpx client to customize it for your use-case. Some common use-cases include support for proxies and transports.

import httpx

from humanloop.client import Humanloop

client = Humanloop(...,
    http_client=httpx.Client(
        proxies="http://my.test.proxy.example.com",
        transport=httpx.HTTPTransport(local_address="0.0.0.0"),
    ),
)

Pagination

Paginated requests will return a SyncPager or AsyncPager, which can be used as generators for the underlying object.

from humanloop.client import Humanloop

client = Humanloop(
    api_key="YOUR_API_KEY",
)
response = client.prompts.list_prompts()
for item in response:
    yield item
# alternatively, you can paginate page-by-page
for page in response.iter_pages():
    yield page

Contributing

While we value open-source contributions to this SDK, this library is generated programmatically. Additions made directly to this library would have to be moved over to our generation code, otherwise they would be overwritten upon the next generated release. Feel free to open a PR as a proof of concept, but know that we will not be able to merge it as-is. We suggest opening an issue first to discuss with us!

On the other hand, contributions to the README are always very welcome!
