Automatic extraction of relevant features from time series:
**The problem**: Hi, great package! Thanks fro developping! I am running the feature extraction on two datasets that have the same IDs but with different length. I use the same...
The current implementation of checking the index of x and y is very unefficient for large data. Using the Panda function Index.equals solves this. 
**The problem**: When trying to `pip install tsfresh` on a M1 Mac, the following error is encountered due to the `matrixprofile` sub-package : ``` × Running setup.py install for matrixprofile...
**The problem**: Hello, I have got a super small dataframe where I ran into an error with feature extraction `features = extract_features(df, column_id="index")` ``` Traceback (most recent call last): File...

Long story short, **extract_features** is not working as expected, it produces a lot of invalid values > [np.nan, np.inf, -np.inf]. Steps to reproduce the issue: 1) Have an input dataframe...
The function `extract_features()` can be very computationally intensive when there are a lot of columns (features) in the rolled data frame. Sometimes I would like to make changes to the...

**The problem**: I couldn't get the result and there is no error message. The output of extract_features is blank. Below is the information of the data:   Any idea?...
