tensorflow 根据节点获取节点前的整张图

1.先获取节点

            output_layer = self.model.get_pooled_output()
            logits = self.tf_instance.matmul(output_layer, output_weights, transpose_b=True)
            logits = self.tf_instance.nn.bias_add(logits, output_bias)
            self.probabilities = self.tf_instance.nn.softmax(logits, axis=-1)

2.获取图

graph = self.probabilities.graph
