from paddle import fluid
import numpy as np

x = fluid.layers.data(name='x', shape=[3], dtype='float32')
output = fluid.layers.sampling_id(x)
print('Compile shape: ', output.shape)

place = fluid.CPUPlace()
exe = fluid.Executor(place=place)
exe.run(fluid.default_startup_program())

feed = {'x': np.array([[0.2, 0.3, 0.5], [0.2, 0.3, 0.5]], dtype='float32')}
output_np = exe.run(feed=feed, fetch_list=[output])[0]

print('Runtime shape: ', output_np.shape)

Compile shape:  (-1, 3)
Runtime shape:  (2,)

Compile shape 应该是(-1)，这个错误会影响后续网络的构建。
