From 389393eb86e4325f3fcc7cd6b4135be2881b0baa Mon Sep 17 00:00:00 2001 From: Pratik Raj Date: Sat, 6 Jun 2020 21:50:19 +0530 Subject: [PATCH] optimize size and time using "--no-cache-dir" Using "--no-cache-dir" flag in pip install ,make sure dowloaded packages by pip don't cached on system . This is a best practise which make sure to fetch ftom repo instead of using local cached one . Further , in case of Docker Containers , by restricing caching , we can reduce image size. In term of stats , it depends upon the number of python packages multiplied by their respective size . e.g for heavy packages with a lot of dependencies it reduce a lot by don't caching pip packages.
