bug描述 Describe the Bug

示例代码: https://www.paddlepaddle.org.cn/documentation/docs/zh/api/paddle/jit/TracedLayer_cn.html
paddlepaddle==2.4.1

代码片段:
import paddle

class ExampleLayer(paddle.nn.Layer):
def init(self):
super(ExampleLayer, self).init()
self._fc = paddle.nn.Linear(3, 10)

def forward(self, input):
    return self._fc(input)

layer = ExampleLayer()
in_var = paddle.uniform(shape=[2, 3], dtype='float32')
out_dygraph, static_layer = paddle.jit.TracedLayer.trace(layer, inputs=[in_var])

您好,目前TracedLayer已经不在支持新动态图了。并且该接口已有废除计划。
目前有两个方案:

  1. export FLAGS_enable_eager_mode=0 切到老动态图下来用(该环境变量在最新develop已失效)
  2. 使用paddle.jit.to_static接口
