Returns

None

Examples

import numpy as np
import paddle.fluid as fluid

with fluid.dygraph.guard():
    inp = np.ones([3, 32, 32], dtype='float32')
    t = fluid.dygraph.base.to_variable(inp)
    fc1 = fluid.FC('fc1', size=4, bias_attr=False, num_flatten_dims=1)
    fc2 = fluid.FC('fc2', size=4)
    ret = fc1(t)
    dy_ret = fc2(ret)
