今天我装了tensorflow-gpu 1.4, keras 2.1.6发现运行keras模型的时候出现了如下的错误：、python
Traceback (most recent call last):
File "models.py", line 24, in <module>
model = NIH()
File "models.py", line 19, in NIH

return tf.nn.softmax(x, axis=axis)
TypeError: softmax() got an unexpected keyword argument 'axis'
就网上说是keras 2.1.6的softmax没有axis这个参数了，因而，我回退了keras版本：spa
pip install keras==2.1
而后程序就不报错误了，完工。
