keras和tensorflow版本？ about seq2seq HOT 10 CLOSED

keras 2.1.5 ~ keras 2.2.2均可。对应的最低的tf版本就行了。

你好，请问你用的tf版本是多少？

from seq2seq.

tf 1.2、1.8、1.10都测试过～

from seq2seq.

我用的tf1.3 报错？
Using TensorFlow backend.
Traceback (most recent call last):

TypeError: softmax() got an unexpected keyword argument 'axis'

from seq2seq.

那只是因为你的keras版本太高，而tf版本过低...两者不配套。你把tf升级到1.8，或者自己修改一下tensorflow_backend.py，将tf.nn.softmax(x, axis=axis)改为tf.nn.softmax(x, axis)

谢谢，刚好的问题解决了，但是还是出现下面这个问题，我用的GPU去跑了，安装的tensorflow是cpu版本的

你有N卡么？装好对应的CUDA和CUDNN环境了？

from seq2seq.

有的，我装的CUDA8.0

from seq2seq.

那我不清楚了，你可以考虑换回普通的LSTM，效果等价的

from seq2seq.

好的，谢谢，我使用普通的可以跑通了
