    Project mention: Publishing dashboards for clients (advice and suggestions plz) | | 2021-02-23

    Many people use Apache Superset this way, in the 'embedded' way: Since its open source, you can customize it extensively.

  • GitHub repo data-science-ipython-notebooks

    Data science Python notebooks: Deep learning (TensorFlow, Theano, Caffe, Keras), scikit-learn, Kaggle, big data (Spark, Hadoop MapReduce, HDFS), matplotlib, pandas, NumPy, SciPy, Python essentials, AWS, and various command lines.

    Project mention: Resources for learning Python from scratch specifically for data ingestion | | 2021-02-13

  • GitHub repo spaCy

    💫 Industrial-strength Natural Language Processing (NLP) in Python

    Project mention: Ask HN: What is your production ML stack like? (2021) | | 2021-02-08

    Here's the ML stack I have been using for my last project:

    - Doing NLP with spaCy ( as I consider it to be the most production ready framework for NLP

    - Annotating datasets with Prodigy (, a paid tool made by the spaCy team

    - Deploying the trained spaCy models onto NLP Cloud (

    - Use the models through the NLP Cloud API in production and enrich my Django application out of it

  • GitHub repo Ray

    An open source framework that provides a simple, universal API for building distributed applications. Ray is packaged with RLlib, a scalable reinforcement learning library, and Tune, a scalable hyperparameter tuning library.

    Project mention: How to get my multi-agents more collaborative? | | 2021-02-15

    QMIX is indeed a great paper. I'm planning on using it with RLLIB on my env, however it asks some work to adapt and understand the subtleties ;) ( such as the agents groups : )

  • GitHub repo ipython

    Official repository for IPython itself. Other repos in the IPython organization contain things like the website, documentation builds, etc.

    Project mention: Question About Embedding Html Audio Tags In | | 2021-02-17

    I've duplicated your error, and it appears to only happen with .wav files. It seems to be a Firefox issue.

  • GitHub repo dash

    Analytical Web Apps for Python, R, Julia, and Jupyter. No JavaScript Required.

    Project mention: Best python GUI to learn? | | 2021-02-23

    If you want a web based dashboard then dash is the way to go

  • GitHub repo streamlit

    Streamlit — The fastest way to build data apps in Python

    Project mention: Which GUI framework do you/would you use for which purposes and why? | | 2021-02-13

    streamlit (Oriented Data science)

  • GitHub repo pytorch-lightning

    The lightweight PyTorch wrapper for high-performance AI research. Scale your models, not the boilerplate.

    Project mention: DDP with model parallelism with multi host multi GPU system | | 2021-02-07
  • GitHub repo gensim

    Topic Modelling for Humans

    Project mention: Koan: A word2vec negative sampling implementation with correct CBOW update | | 2021-01-02

    Apparently it did:

  • GitHub repo allennlp

    An open-source NLP research library, built on PyTorch.

    Project mention: AllenNLP v2.0.0 | | 2021-01-27
  • GitHub repo TFLearn

    Deep learning library featuring a higher-level API for TensorFlow.

  • GitHub repo nni

    An open source AutoML toolkit for automate machine learning lifecycle, including feature engineering, neural architecture search, model compression and hyper-parameter tuning.

    Project mention: How we were able to achieve hyper-parameter tuning (HPT) for deep learning workflows at 1.5x faster in our clusters and 3x cheaper on AWS | | 2021-02-23

    To tackle the problem of long and expensive HPT workflows, our team at Petuum collaborated with Microsoft to integrate AdaptDL with Neural Network Intelligence (NNI). AdaptDL is an open-source tool in the CASL (Composable, Automatic, and Scalable Learning) ecosystem. AdaptDL offers adaptive resource management for distributed clusters, and reduces the cost of deep learning workloads ranging from a few training/tuning trials to thousands. NNI from the Microsoft open-source community, is a toolkit for automatic machine learning (AutoML) and hyper-parameter tuning.

  • GitHub repo seaborn

    Statistical data visualization using matplotlib

  • GitHub repo dvc

    🦉Data Version Control | Git for Data & Models

    Project mention: SnowFS – a fast, scalable version control file storage for graphic files | | 2021-02-20

    Very interesting. I'd like to learn more about how it works. How does this compare to DVC[1], for instance?

    I'll throw in a shameless plug for my tool in this area, Dud[2]. Dud is to DVC what Flask is to Django.

    Are the mentioned benchmarks published somewhere?


  • GitHub repo Prefect

    The easiest way to automate your data

    Project mention: [D] Software stack to replicate Azure ML / Google Auto ML on premise | | 2021-02-03

    Update: So far I started using Prefect ( With this I can work on my local computer, submit code to Azure Blob Storage and the Prefect server. After which a agent (worker) runs the code. Logging/Metrics are not implemented yet, I might use MLFlow for this ( Furthermore, there is still a dependency on a cloud solution to store your Flows (programs) to run them on agents.

  • GitHub repo boltons

    🔩 Like builtins, but boltons. 250+ constructs, recipes, and snippets which extend (and rely on nothing but) the Python standard library. Nothing like Michael Bolton.

  • GitHub repo cookiecutter-data-science

    A logical, reasonably standardized, but flexible project structure for doing and sharing data science work.

    Project mention: How do you handle raw + clean data? | | 2021-02-15

    Take a look at for a well structured project layout and then make 1 script for each step (1-2-3), so that you can reproduce/modify it easily.

  • GitHub repo pyod

    (JMLR'19) A Python Toolbox for Scalable Outlier Detection (Anomaly Detection)

    Project mention: PyOD: ~50 anomaly detection algorithms in one framework. | | 2021-01-25
  • GitHub repo best-of-ml-python

    🏆 A ranked list of awesome machine learning Python libraries. Updated weekly.

    Project mention: best-of-python: A ranked list of awesome Python libraries and tools | | 2021-01-14

    Here ya go:

  • GitHub repo metaflow

    Build and manage real-life data science projects with ease.

    Project mention: Netflix's Metaflow: Reproducible machine learning pipelines | | 2020-12-21

    has anyone done a comparison of ML pipelines from a devops centric perspective ?

    For example, Metaflow doesnt support kubernetes today -

    so ultimately the scale up story in most of these management tools is iffy.

    I previously asked about kubeflow here - . Seems people think its pretty "horrendous". It seems most of these tools assume a very specialised devops team who will work around the ml tool...rather than the ml tool making this easy.

  • GitHub repo great_expectations
