model.save - Githubissues

Wenqianqian123 commented 6 months ago

使用configs.longterm_forecast下的Crossformer_ECL.yml配置文件，运行train.py脚本，执行训练。发现没有保存模型的代码。在model.fit(ts_train,ts_val)代码后加入model.save("./Crossformer",network_model=Ture,dygraph_to_static=True).运行报错：[ERROR] ValueError: error occurred while saving or dygraph_to_static network_model: Crossformer, err: In transformed code: File "/home/PaddleTS-main/paddlets/models/forecasting/dl/Crossformer.py", line 84, in forward x_seq = self.enc_value_embedding(x_seq) File "/home/PaddleTS-main/paddlets/models/forecasting/dl/_crossformer/embedding.py", line 16, in forward 'b (seg_num seg_len) d -> (b d seg_num) seg_len', seg_len=self.

您好目前并不是所有模型支持静态图导出，Crossformer没有做静态图导出的适配。可以直接运行model.save("./Crossformer"）尝试保存动态图模型。

谢谢您的回复，请问在paddleTS模型库中的几个模型中，哪个模型做的有静态图导出的适配

您好，RNN，DLinear等早期的模型一般都支持静态导出。
