报错：TypeError: Cannot convert Type TensorType(int32, matrix) (of Variable Subtensor{int64:int64:}.0) into Type TensorType(int32, vector). You can try to manually convert Subtensor{int64:int64:}.0 into a TensorType(int32, vector).
Reason: The shape of the numpy array is not directly converted to (-1,) and is directly used by theano. The 1-dimensional numpy array will be regarded as a matrix by theano, not a vector. So you need to manually convert it first.
solve:
Method 1: test_raw_y.flatten ()
Method two: test_raw_y.reshape ((-1))
