 ### 2. create a forecaster.
-We provide two methods for creating Forecaster.
-#### 1. Create a Forecaster using Forecaster.from_tsdataset(Highly recommended)
-`from_tsdataset` is a class method, so you can call `Forecsater.from_tsdataset` directly, then enter a `TSDataset` instance.
-`TSDataset` is a built-in time series preprocessing class, more info please refer to [how to use TSDataset and get_public_dataset](xxxx).
-If your tsdataset has used the `roll` or `to_torch_data_loader` methods,
-you do not need to specify `past_seq_len` and `future_seq_len` for from_tsdataset, otherwise you must specify both.
-You can also specify the hyperparameters of the model, such as lr, dropout etc.
-The simplest usage of "from_tsdataset" is given below. More info, please refer to [from_tsdataset](xxxx).

-training: After you have created the forecaster, you can train your model, Please refer to [how to train]()
-distributed: When your data volume is large and it is difficult to complete on a single machine, we also provide distributed training, please refer to [train model distributed on a cluster]()
