Erick Friis	1bc35f61cb	CLI 0.0.14, Uvicorn update and no more [serve] (#12845 ) Calls uvicorn directly from cli: Reload works if you define app by import string instead of object.

Praveen Venkateswaran	21eeba075c	enable the device_map parameter in huggingface pipeline (#12731 ) ### Enabling `device_map` in HuggingFacePipeline For multi-gpu settings with large models, the [accelerate](https://huggingface.co/docs/accelerate/usage_guides/big_modeling#using--accelerate) library provides the `device_map` parameter to automatically distribute the model across GPUs / disk. The [Transformers pipeline](`3520e37e86/src/transformers/pipelines/__init__.py (L543)`) enables users to specify `device` (or) `device_map`, and handles cases (with warnings) when both are specified. However, Langchain's HuggingFacePipeline only supports specifying `device` when calling transformers which limits large models and multi-gpu use-cases. Additionally, the [default value](`8bd3ce59cd/libs/langchain/langchain/llms/huggingface_pipeline.py (L72)`) of `device` is initialized to `-1` , which is incompatible with the transformers pipeline when `device_map` is specified. This PR addresses the addition of `device_map` as a parameter , and solves the incompatibility of `device = -1` when `device_map` is also specified. An additional test has been added for this feature. Additionally, some existing tests no longer work since 1. `max_new_tokens` has to be specified under `pipeline_kwargs` and not `model_kwargs` 2. The GPT2 tokenizer raises a `ValueError: Pipeline with tokenizer without pad_token cannot do batching`, since the `tokenizer.pad_token` is `None` ([related issue](https://github.com/huggingface/transformers/issues/19853) on the transformers repo). This PR handles fixing these tests as well. Co-authored-by: Praveen Venkateswaran <praveen.venkateswaran@ibm.com>	10 months ago
Mark Bell	3276aa3e17	__getattr__ should rase AttributeError not ImportError on missing attributes (#12801 ) [The python spec](https://docs.python.org/3/reference/datamodel.html#object.__getattr__) requires that `__getattr__` throw `AttributeError` for missing attributes but there are several places throwing `ImportError` in the current code base. This causes a specific problem with `hasattr` since it calls `__getattr__` then looks only for `AttributeError` exceptions. At present, calling `hasattr` on any of these modules will raise an unexpected exception that most code will not handle as `hasattr` throwing exceptions is not expected. In our case this is triggered by an exception tracker (Airbrake) that attempts to collect the version of all installed modules with code that looks like: `if hasattr(mod, "__version__"):`. With `HEAD` this is causing our exception tracker to fail on all exceptions. I only changed instances of unknown attributes raising `ImportError` and left instances of known attributes raising `ImportError`. It feels a little weird but doesn't seem to break anything.	10 months ago
