'尝试升级使用弃用的转换参数指定的输入文件'是什么意思？

Question

我目前正试图训练我的第一个网与Caffe。我得到以下输出：

是什么

Attempting to upgrade input file specified using deprecated transform parameters/V1LayerParameter

是什么意思？我究竟在哪里使用了某些已弃用的东西？我应该用什么来代替？

最近，输入转换（缩放/裁剪等）从IMAGE_DATA层分离成单独的对象：数据转换器。此更改影响了原始缓冲区语法和IMAGE_DATA图层的语法。

看起来好像你的first_net.prototxt是旧格式，Caffe会将它转换为新格式。

您可以使用./build/tools/upgrade_net_proto_text（对于原型文件）和./build/tools/upgrade_net_proto_binary（对于binaryproto文件）手动执行此转换。
