TuneError: ('Trials did not complete', [train_func_19925_00004])

I'm trying to implement auto_ts on my multivariate time series data using Lstm , while fitting it is giving the following error.

Data is in this format

We may need more information to identify the root cause. Could you provide the detail in your /tmp/autots_estimator/autots_estimator/train_func_19925_00004/error.txt?

Hi, thanks for your feedback!

Please also check if your data df is sorted. From the snapshot, it seems to be unordered.

bigdl-chronos is our latest project for scalable time series toolkit with automl, it's recommended to use it instead of analytics-zoo.

Sure, I'll make the corrections and try again
