From f82515800c0c0f3b85f1dfaf56fb5690e4c70681 Mon Sep 17 00:00:00 2001 From: Haihao Shen Date: Mon, 28 Jan 2019 11:11:42 +0800 Subject: [PATCH] Enable INT8 Calibration Unit Test for MobileNet-V1 (#15539) * Enable mobilenet UT in separate test class; use download cache by paddle download utility and cache unzip; and fix typo; test=develop * Extract cache_unzipping function for reuse; format code style; test=develop * Simplify the test code by define a combined function for both downloading and unzipping;
