theano concatenate 实例

import theanoimport numpy as npimport theano.tensor as Tones = theano.shared(np.float32([[1,2,3],[4,5,6],[7,8,9]]))print(ones.get_value())result = T.concatenate([ones,ones],axis=0)print(result.eval())result = T.concatenate([ones,ones],axis=1)print(result.eval())

结果：

[[ 1. 2. 3.]
[ 4. 5. 6.]
[ 7. 8. 9.]]

[[ 1. 2. 3.]
[ 4. 5. 6.]
[ 7. 8. 9.]
[ 1. 2. 3.]
[ 4. 5. 6.]
[ 7. 8. 9.]]

[[ 1. 2. 3. 1. 2. 3.]
[ 4. 5. 6. 4. 5. 6.]
[ 7. 8. 9. 7. 8. 9.]]
