Tsfresh: wrong dependency for 0.11.2

[ian-contiamo]

This commit appears to have broken feature selection:
https://github.com/blue-yonder/tsfresh/commit/68a64a0f8ebc27359177b10d9898a800502983a0

I get the following error:

from tsfresh import extract_features, select_features
features_filtered = select_features(train_features, train_target)

RemoteTraceback: 
"""

I believe the requirement for scipy is outdated:

Cheers!

Oh, I added scipy to our travis pipeline to catch those kind of errors. Thanks for reporting it

[ian-contiamo]

Thank you!

[MaxBenChrist]

Will be fixed in 0.11.3

I meet this problem too ,plz tell me how to solve it .many thanks~

[cliffrunner]

I am having the same issue. Is there a workaround? Thanks.

[MaxBenChrist]

Hi @zhangyouchang and @cliffrunner , you will have to update scipy to 1.2.0, the error should vanish afterwards

[cliffrunner]

Hi @MaxBenChrist , my scipy version is 1.2 but the problem persists.

@MaxBenChrist , For tsfresh 0.11.2 I updated scipy manually to version 1.3.0 - the error is still there.
Update: It actually works, but kernel/interpreter restart needed.
