rahul003 commented on issue #8671: Discussion and troubleshooting on PyPI (pip) installation URL: https://github.com/apache/incubator-mxnet/issues/8671#issuecomment-386770513 @szha Can we turn on the USE_LIBJPEG_TURBO flag. I find that it helps improve the speed of IO pipeline significantly? Results for Resnet50 v1 Imagenet, 480px resized data, batch size 1920, float16, symbolic: Current: 3600samples/sec With libjpeg-turbo: 4600samples/sec As an example, Here's how I used LIBJPEG_TURBO on ubuntu. ``` sudo apt-get install autoconf automake libtool nasm JPEG_TURBO_VERSION=1.5.2 && \ wget -q -O - https://github.com/libjpeg-turbo/libjpeg-turbo/archive/${JPEG_TURBO_VERSION}.tar.gz | tar -xzf - && \ cd libjpeg-turbo-${JPEG_TURBO_VERSION} && \ autoreconf -fiv && \ ./configure --enable-shared --prefix=/usr 2>&1 >/dev/null && \ sudo make -j"$(nproc)" install 2>&1 >/dev/null && \ rm -rf libjpeg-turbo-${JPEG_TURBO_VERSION} ``` Flags `USE_LIBJPEG_TURBO=1 USE_LIBJPEG_TURBO_PATH=/usr`
