Streamlit is an open-source app framework that enables Machine Learning and Data Science teams to create beautiful web apps in minutes. It is a Python-based library specifically designed for machine learning engineers. Streamlit lets you turn data scripts into shareable web apps in minutes, not weeks. It is all Python, open-source, and free! In comparison to Flask, for relatively simple apps, Streamlit would suffice. However, if the user requires a more secure full-fledged app, Flask would be the better option. Streamlit components have two parts, a frontend that gets rendered in Streamlit apps via an iframe tag and a Python API that Streamlit client apps use to instantiate the frontend and communicate with it. Overall, Streamlit is an excellent option for creating quick data apps without having to spend weeks on the app's development.
Pydantic is a Python library used for data validation and settings management via Python type annotations. It enforces type hints at runtime, making it user-friendly by providing helpful error messages when data is incorrect. It is widely used and downloaded millions of times a day by thousands of developers worldwide. Pydantic allows custom data types to be defined, and it has a custom validation mechanism, making it an easy-to-use and efficient tool for parsing requests and responses. In addition, Pydantic is often used in the FastAPI framework as it has built-in support for JSON encoding and decoding. Compared to other data validation libraries, such as marshmallow, Pydantic returns Python objects directly, making it a powerful tool in data modeling and parsing. It provides the dataclass decorator which creates dataclasses with input data parsing and validation. Pydantic also has a built-in support for JSON encoding and decoding, which makes parsing JSON data effortless.
Optuna is an automatic hyperparameter optimization software framework that is designed for machine learning. It features an imperative, define-by-run style interface and supports various state-of-the-art optimization algorithms, including Bayesian optimization. Optuna enables automatic searches and finds optimal hyperparameters by trial and error, which leads to excellent performance. Moreover, it supports imperative parameter definition, which provides more flexibility, and features a pruning mechanism that monitors each trial's learning curves and determines the sets of hyperparameters that will not lead to good results. Currently, the software can be used in Python and is available on GitHub. Overall, Optuna is a powerful tool that is widely used and highly recommended for hyperparameter optimization in the field of machine learning.
