Python 3. Dead kernel after catch22 usage about catch22

[chlubba]

Hello Migal,

sorry to hear you are experiencing trouble with catch22. What do you mean by "amount of data is equal to 2"? catch22_all is only suited for univariate time series that are stored in a vector. Did you try it without the apply function of pandas?

What do you mean by "amount of data is equal to 2"?

I mean case when group_data.shape[0] == 2

Did you try it without the apply function of pandas

Sure. This code have the same behavior:
buf = pd.DataFrame(catch22.catch22_all(group_data[column_name]), dtype=np.float64)

Please try it without the direct use of pandas data frames by converting the column to a numpy array. I'll try to make catch22 pandas-ready but I guess for now you'll have to stick with Python lists or numpy arrays.

I understand your concerns.

I try to set list as input into the catch22 functions and I have dead kernel as result. Here is the code:

functions = dir(catch22)[:-11] # get all functions from catch22
i=0
func = getattr(catch22, functions[i])
func(list(group_data[column_name]))

Have the same problem, kernel dies if apply function on array with len 1 or 2.
Could be useful to add exception for it.
