Introduction

A fast ELMo implementation with features:

  • Lower execution overhead. The core components are reimplemented in Libtorch in order to reduce the Python execution overhead (45% speedup).
  • A more flexible design. By redesigning the workflow, the user could extend or change the ELMo behavior easily.

Benchmark

Hardware:

  • CPU: i7-7800X
  • GPU: 1080Ti

Options:

  • Batch size: 32
  • Warm up iterations: 20
  • Test iterations: 1000
  • Word length: [1, 20]
  • Sentence length: [1, 30]
  • Random seed: 10000

Usage

Please install torch==1.0.0 first. Then, simply run this command to install.

.. code-block:: bash

pip install pytorch-fast-elmo

FastElmo should have the same behavior as AllenNLP's ELMo.

.. code-block:: python

from pytorch_fast_elmo import FastElmo, batch_to_char_ids

options_file = '/path/to/elmo_2x4096_512_2048cnn_2xhighway_options.json'
weight_file = '/path/to/elmo_2x4096_512_2048cnn_2xhighway_weights.hdf5'

elmo = FastElmo(options_file, weight_file)

sentences = [['First', 'sentence', '.'], ['Another', '.']]
character_ids = batch_to_ids(sentences)

embeddings = elmo(character_ids)

Use FastElmoWordEmbedding if you have disabled char_cnn in bilm-tf, or have exported the Char CNN representation to a weight file.

.. code-block:: python

from pytorch_fast_elmo import FastElmoWordEmbedding, load_and_build_vocab2id, batch_to_word_ids

options_file = '/path/to/elmo_2x4096_512_2048cnn_2xhighway_options.json'
weight_file = '/path/to/elmo_2x4096_512_2048cnn_2xhighway_weights.hdf5'

vocab_file = '/path/to/vocab.txt'
embedding_file = '/path/to/cached_elmo_embedding.hdf5'

elmo = FastElmoWordEmbedding(
        options_file,
        weight_file,
        # Could be omitted if the embedding weight is in `weight_file`.
        word_embedding_weight_file=embedding_file,
)
vocab2id = load_and_build_vocab2id(vocab_file)

sentences = [['First', 'sentence', '.'], ['Another', '.']]
word_ids = batch_to_word_ids(sentences, vocab2id)

embeddings = elmo(word_ids)

CLI commands:

.. code-block:: bash

# Cache the Char CNN representation.
fast-elmo cache-char-cnn ./vocab.txt ./options.json ./lm_weights.hdf5 ./lm_embd.hdf5

# Export word embedding.
fast-elmo export-word-embd ./vocab.txt ./no-char-cnn.hdf5 ./embd.txt

Bump wheel from 0.32.3 to 0.38.1

opened on 2022-12-26 20:50:47 by dependabot[bot]

Bumps wheel from 0.32.3 to 0.38.1.

Changelog

Sourced from wheel's changelog.

Release Notes

UNRELEASED

  • Updated vendored packaging to 22.0

0.38.4 (2022-11-09)

  • Fixed PKG-INFO conversion in bdist_wheel mangling UTF-8 header values in METADATA (PR by Anderson Bravalheri)

0.38.3 (2022-11-08)

  • Fixed install failure when used with --no-binary, reported on Ubuntu 20.04, by removing setup_requires from setup.cfg

0.38.2 (2022-11-05)

  • Fixed regression introduced in v0.38.1 which broke parsing of wheel file names with multiple platform tags

0.38.1 (2022-11-04)

  • Removed install dependency on setuptools
  • The future-proof fix in 0.36.0 for converting PyPy's SOABI into a abi tag was faulty. Fixed so that future changes in the SOABI will not change the tag.

0.38.0 (2022-10-21)

  • Dropped support for Python < 3.7
  • Updated vendored packaging to 21.3
  • Replaced all uses of distutils with setuptools
  • The handling of license_files (including glob patterns and default values) is now delegated to setuptools>=57.0.0 (#466). The package dependencies were updated to reflect this change.
  • Fixed potential DoS attack via the WHEEL_INFO_RE regular expression
  • Fixed ValueError: ZIP does not support timestamps before 1980 when using SOURCE_DATE_EPOCH=0 or when on-disk timestamps are earlier than 1980-01-01. Such timestamps are now changed to the minimum value before packaging.

0.37.1 (2021-12-22)

  • Fixed wheel pack duplicating the WHEEL contents when the build number has changed (#415)
  • Fixed parsing of file names containing commas in RECORD (PR by Hood Chatham)

Bump pip from 19.0.1 to 21.1

opened on 2021-11-15 17:48:03 by dependabot[bot]

Bumps pip from 19.0.1 to 21.1.

Changelog

Sourced from pip's changelog.

21.1 (2021-04-24)

Process

  • Start installation scheme migration from distutils to sysconfig. A warning is implemented to detect differences between the two implementations to encourage user reports, so we can avoid breakages before they happen.

Features

  • Add the ability for the new resolver to process URL constraints. ([#8253](https://github.com/pypa/pip/issues/8253) <https://github.com/pypa/pip/issues/8253>_)
  • Add a feature --use-feature=in-tree-build to build local projects in-place when installing. This is expected to become the default behavior in pip 21.3; see Installing from local packages <https://pip.pypa.io/en/stable/user_guide/#installing-from-local-packages>_ for more information. ([#9091](https://github.com/pypa/pip/issues/9091) <https://github.com/pypa/pip/issues/9091>_)
  • Bring back the "(from versions: ...)" message, that was shown on resolution failures. ([#9139](https://github.com/pypa/pip/issues/9139) <https://github.com/pypa/pip/issues/9139>_)
  • Add support for editable installs for project with only setup.cfg files. ([#9547](https://github.com/pypa/pip/issues/9547) <https://github.com/pypa/pip/issues/9547>_)
  • Improve performance when picking the best file from indexes during pip install. ([#9748](https://github.com/pypa/pip/issues/9748) <https://github.com/pypa/pip/issues/9748>_)
  • Warn instead of erroring out when doing a PEP 517 build in presence of --build-option. Warn when doing a PEP 517 build in presence of --global-option. ([#9774](https://github.com/pypa/pip/issues/9774) <https://github.com/pypa/pip/issues/9774>_)

Bug Fixes

  • Fixed --target to work with --editable installs. ([#4390](https://github.com/pypa/pip/issues/4390) <https://github.com/pypa/pip/issues/4390>_)
  • Add a warning, discouraging the usage of pip as root, outside a virtual environment. ([#6409](https://github.com/pypa/pip/issues/6409) <https://github.com/pypa/pip/issues/6409>_)
  • Ignore .dist-info directories if the stem is not a valid Python distribution name, so they don't show up in e.g. pip freeze. ([#7269](https://github.com/pypa/pip/issues/7269) <https://github.com/pypa/pip/issues/7269>_)
  • Only query the keyring for URLs that actually trigger error 401. This prevents an unnecessary keyring unlock prompt on every pip install invocation (even with default index URL which is not password protected). ([#8090](https://github.com/pypa/pip/issues/8090) <https://github.com/pypa/pip/issues/8090>_)
  • Prevent packages already-installed alongside with pip to be injected into an isolated build environment during build-time dependency population. ([#8214](https://github.com/pypa/pip/issues/8214) <https://github.com/pypa/pip/issues/8214>_)
  • Fix pip freeze permission denied error in order to display an understandable error message and offer solutions. ([#8418](https://github.com/pypa/pip/issues/8418) <https://github.com/pypa/pip/issues/8418>_)
  • Correctly uninstall script files (from setuptools' scripts argument), when installed with --user. ([#8733](https://github.com/pypa/pip/issues/8733) <https://github.com/pypa/pip/issues/8733>_)
  • New resolver: When a requirement is requested both via a direct URL (req @ URL) and via version specifier with extras (req[extra]), the resolver will now be able to use the URL to correctly resolve the requirement with extras. ([#8785](https://github.com/pypa/pip/issues/8785) <https://github.com/pypa/pip/issues/8785>_)
  • New resolver: Show relevant entries from user-supplied constraint files in the error message to improve debuggability. ([#9300](https://github.com/pypa/pip/issues/9300) <https://github.com/pypa/pip/issues/9300>_)
  • Avoid parsing version to make the version check more robust against lousily debundled downstream distributions. ([#9348](https://github.com/pypa/pip/issues/9348) <https://github.com/pypa/pip/issues/9348>_)
  • --user is no longer suggested incorrectly when pip fails with a permission error in a virtual environment. ([#9409](https://github.com/pypa/pip/issues/9409) <https://github.com/pypa/pip/issues/9409>_)
  • Fix incorrect reporting on Requires-Python conflicts. ([#9541](https://github.com/pypa/pip/issues/9541) <https://github.com/pypa/pip/issues/9541>_)
