代码说明:

本代码用于测试QT环境是否安装成功,接下来解压文件:xz –d qt-everywhere-opensource-src-5.3.0.tar.xz  得到qt-everywhere-opensource-src-5.3.0.tar 继续解压:tar –xvf qt-everywhere-opensource-src-5.3.0进入qt目录,修改配置文件。本人是s3c2440arm9指令集是armv4t。修改源码包目录下的/qtbase/mkspecs/linux-arm-gnueabi-g++/qmake.conf文件:MAKEFILE_GENERATOR     = UNIXCONFIG                += incrementalQMAKE_INCREMENTAL_STYLE = sublib/********************************新加入***************************/QT_QPA_DEFAULT_PLATFORM = linuxfb QMAKE_CFLAGS_RELEASE   +=-O2 -march=armv4t#这里指出指令局。跟芯片有关系,根据芯片改正-march=?  -O2是编译器的优化等级QMAKE_CXXFLAGS_RE

下载说明:请别用迅雷下载,失败请重下,重下不扣分!

  • kaggle_diabetic-master
    说明:  A commented bash script to generate our final 2nd place solution can be found in make_kaggle_solution.sh. Running all the commands sequentially will probably take 7 - 10 days on recent consumer grade hardware. If you have multiple GPUs you can speed things up by doing training and feature extraction for the two networks in parallel. However, due to the computationally heavy data augmentation it may be far less than twice as fast especially when working with 512x512 pixel input images. You can also obtain a quadratic weighted kappa score of 0.839 on the private leaderboard by just training the 4x4 kernel networks and by performing only 20 feature extraction iterations with the weights that gave you the best MSE validation scores during training. The entire ensemble only achieves a slightly higher score of 0.845.
