From b9d94183348c6f72f79aa1fa69ce36147eda3660 Mon Sep 17 00:00:00 2001 From: Pratik raj Date: Sat, 13 Jun 2020 07:25:32 +0530 Subject: 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.
