Python utilities used by Deep Procedural Intelligence
Project description
DPU Utilities 
This contains a set of utilities used across projects of the DPU team.
Python
Stored in the python subdirectory, published as the dpu-utils package.
Installation
pip install dpu-utils
Overview
Below you can find an overview of the utilities included. Detailed documentation is provided at the docstring of each class.
Generic Utilities dpu_utils.utils
ChunkWriterprovides a convenient API for writing output in multiple parts (chunks).RichPathan API that abstract local and Azure Blob paths in your code.*IteratorWrappers that can parallelize and shuffle iterators.{load,save}_json[l]_gzconvenience API for loading and writing.json[l].gzfiles.git_tag_runtags the current working directory git the state of the code.run_and_debugwhen an exception happens, start a debug session. Usually a wrapper of__main__.
General Machine Learning Utilities dpu_utils.mlutils
Vocabularymap elements into unique integer ids and back. Commonly used in machine learning models that work over discrete data (e.g. words in NLP). Contains methods for converting an list of tokens into their "tensorized" for of integer ids.BpeVocabularya vocabulary for machine learning models that employs BPE (viasentencepiece).CharTensorizerconvert character sequences into into tensors, commonly used in machine learning models whose input is a list of characters.
Code-related Utilities dpu_utils.codeutils
split_identifier_into_parts()split identifiers into subtokens on CamelCase and snake_case.Lattice,CSharpLatticerepresent lattices and useful operations on lattices in Python.get_language_keywords()an API to retrieve the keyword tokens for many programming languages.deduplication.DuplicateDetectorAPI to detects (near)duplicates in codebases. See also here for a command line tool.
TensorFlow 1.x Utilities dpu_utils.tfutils
get_activationretrieve activations function by name.GradRatioLoggingOptimizera wrapper around optimizers that logs the ratios of grad norms to parameter norms.TFVariableSaversave TF variables in an object that can be pickled.
Unsorted segment operations following TensorFlow's unsorted_segment_sum operations:
TensorFlow 2.x Utilities dpu_utils.tf2utils
get_activation_function_by_nameretrieve activation functions by name.geluThe GeLU activation function.MLPAn MLP layer.
Unsorted segment operations following TensorFlow's unsorted_segment_sum operations:
TensorFlow Models dpu_utils.tfmodels
SparseGGNNa sparse GGNN implementation.AsyncGGNNan asynchronous GGNN implementation.
These models have not been tested with TF 2.0.
PyTorch Utilities dpu_utils.ptutils
BaseComponenta wrapper abstract class aroundnn.Modulethat takes care of essential elements of most neural network components.ComponentTrainera training loop forBaseComponents.
Command-line tools
Approximate Duplicate Code Detection
You can use the deduplicationcli command to detect duplicates in pre-processed source code, by invoking
deduplicationcli DATA_PATH OUT_JSON
where DATA_PATH is a file containing tokenized .jsonl.gz files and OUT_JSON is the target output file.
For more options look at --help.
An exact (but usually slower) version of this can be found here along with code to tokenize Java, C#, Python and JavaScript into the relevant formats.
Tests
Run the unit tests
python setup.py test
Generate code coverage reports
# pip install coverage
coverage run --source dpu_utils/ setup.py test && \

The resulting HTML file will be in htmlcov/index.html.
.NET
Stored in the dotnet subdirectory.
Generic Utilities:
Microsoft.Research.DPU.Utils.RichPath: a convenient way of using both paths and Azure paths in your code.
Code-related Utilities:
Microsoft.Research.DPU.CSharpSourceGraphExtraction: infrastructure to extract Program Graphs from C# projects.
