Chronos : fit_loop epoch not reset properly for Autoformer

2

``` autoformer = AutoformerForecaster(past_seq_len=look_back, future_seq_len=horizon, input_feature_num=321, output_feature_num=321, label_len=label_len, freq='h', seed=1024, loss="mse", metrics=['mae', 'mse', 'mape'], lr=0.0001, d_model=128, d_ff=64, e_layer=2, n_head=2) autoformer.fit(train_loader, epochs=2, batch_size=32) autoformer.trainer.fit(autoformer.internal, train_loader) ``` and the second fit is...

Although I fixed seed in this code(https://github.com/intel-analytics/BigDL/blob/main/python/chronos/use-case/electricity/autoformer.py), the results after each fit are different, and the gap is very large (MSE: 0.26-0.4).

Nano : automatically detect redundant inputs and feedback to users

Also to fix https://github.com/intel-analytics/BigDL/issues/4970, here add automatic detection of redundant input names in trace with onnxruntime.

I see on this website https://grouplens.org/datasets/movielens/ ml-20m.zip is 196MB.

Now user use `predict()` under two situations: 1. they use predict as evaluate, so the data should contain (x, y) 2. they just do inference, so the data should only...

Chronos : List the input data type of forecaster and locate some dismatch

Nowdays, input data types for different methods in BaseForecaster and AutoformerForecaster is different and is confusing. The following table lists the support data types of each method: | Method |...
