from paddle import fluid
import numpy as np

inputs = fluid.layers.data(name='inputs',shape=[], dtype='int32')
outputs = fluid.layers.unsqueeze(inputs, axes=0)

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

outputs_np = exe.run(feed={'inputs': np.array([1], dtype='int32')},
                     fetch_list=[outputs])[0]
print(outputs_np)

异常信息如下：
