Make sure you have called identify_*()
method before calling remove
method.
from feature-selector.
I am facing the same issue even I call fs.identify_collinear(correlation_threshold = 0.95) train_removed = fs.remove(methods = 'all')
`2 features with a correlation magnitude greater than 0.95.
AttributeError Traceback (most recent call last)
in
1 fs.identify_collinear(correlation_threshold = 0.95)
----> 2 train_removed = fs.remove(methods = 'all')
~\AppData\Roaming\Python\Python36\site-packages\feature_selector\feature_selector.py in remove(self, methods, keep_one_hot)
460
461 # Need to use one-hot encoded data as well
--> 462 data = self.data_all
463
464 print('{} methods have been run\n'.format(list(self.ops.keys())))
AttributeError: 'FeatureSelector' object has no attribute 'data_all'
`
also when I try to use one method I get below error, even I ran the method before :
`
fs.identify_collinear(correlation_threshold = 0.95)
2 features with a correlation magnitude greater than 0.95.
train_removed = fs.remove(methods="collinear")
NotImplementedError Traceback (most recent call last)
in
----> 1 train_removed = fs.remove(methods="collinear")
~\AppData\Roaming\Python\Python36\site-packages\feature_selector\feature_selector.py in remove(self, methods, keep_one_hot)
480 # Check to make sure the method has been run
481 if method not in self.ops.keys():
--> 482 raise NotImplementedError('%s method has not been run' % method)
483
484 # Append the features identified for removal
NotImplementedError: c method has not been run
