Whether you need to quickly sort an Array, perform advanced filtering, make mathematical calculations, execute a Regular Expression on a string, escape HTML, check the type of a value, or do one of many more common tasks, Power Assist makes it simple. No more long, complex expressions, ...
Our first model, the 1.3 billion parameter Phi-1 (opens in new tab), achieved state-of-the-art performance on Python coding among existing SLMs (specifically on the HumanEval and MBPP benchmarks). We then extended our focus to common sense reasoning and language understanding and created a...
You need Python 3.6 or above. From the terminal (or Anaconda prompt in Windows), enter: pip install -U ppscore Getting started The examples refer to the newest version (1.2.0) of ppscore.See changes First, let's create some data: ...
The data scientist must explicitly generate the schema file using Python. This schema file must be included in the deployed web service for Machine Learning models. To automatically generate the schema for web service, you must provide a sample of the input/output in the entry script for the ...
