keras编译出现 ImportError: cannot import name Merge
源码来自
AlexNet-Experiments-Keras
编译的时候出现了一些问题，记录一下
==========================
经过查阅资料，把alexnet_base.py和customlayer.py里都修改了一下
from keras.layer import merge就可以了
全部改成merge（代码段里相应的也需要修改）
全部从keras.layer里import，而不是keras.layers.core
============================
首先我是用的是tensorflow作为backend，一开始再jupyter notebook上直接编译的时候
ValueError: You are tring to use the old GPU back-end. It was removed from Theano. Use device=cuda* now. See https://github.com/Theano/Theano/wiki/Converting-to-the-new-gpu-back-end%28gpuarray%29 for more information.打开code/alexnet_base.py
修改了
os.environ['THEANO_FLAGS'] = "device=cuda×" /home/chutz/anaconda3/lib/python3.6/site-packages/h5py/__init__.py:36: FutureWarning: Conversion of the second argument of issubdtype from `float` to `np.floating` is deprecated. In future, it will be treated as `np.float64 == np.dtype(float).type`.

我就注释了import theano as T，如果有知道原因的大神还请不吝赐教
再运行就出现了
