### 🐛 Bug Report There are few cases where we create a new `TSDataset` from the old one and assign the same attributes instead of copying them: * [TSDataset.make_future](https://github.com/tinkoff-ai/etna/blob/master/etna/datasets/tsdataset.py#L237) *...

### 🐛 Bug Report Currently `SeasonalMovingAverageModel` and `MovingAverageModel` don't pass some tests written in `test_inference`. Try also to make sure that in-sample predictions work as expected. ### Expected behavior Tests...

### 🚀 Feature Request We want to add title for plots in `etna.analysis`. ### Proposal 1. Find out whether `plt.show()` is necessary and if not, remove it from all the...

### 🐛 Bug Report In some circumstances we can't predict first point with `CatBoostPerSegmentModel`. ### Expected behavior First point is predicted. ### How To Reproduce ```python import pandas as pd...

### 🚀 Feature Request We can make class `MeanEncoderTransform` that will work with any feature. In that case `MeanSegmentEncoderTransform` can be replace with `SegmentEncoderTransform` + `MeanEncoderTransform`. ### Motivation It will...

### 🚀 Feature Request Merge `master` branch into `inference` branch. Or make a rebase. ### Proposal Merge `master` branch into `inference` branch. Or make a rebase. ### Test cases Make...

### 🐛 Bug Report Currently some tests in `test_inference/test_forecast` doesn't pass for `RNNModel`, it should be fixed. Tests to fix: * `TestForecastInSampleFullNoTarget`, * `TestForecastOutSampleSuffix`. ### Expected behavior Tests pass. ###...
