Pylint: Pylint giving a false positive E1101 for sklearn

[kraftpunk97]

Steps to reproduce

1. Tested it out on the following code:

from sklearn.datasets import load_iris
iris = load_iris()
print(iris.feature_names)
print(iris.target_names)
print(iris.data[0])
print(dir(iris))

Output in terminal -

['sepal length (cm)', 'sepal width (cm)', 'petal length (cm)', 'petal width (cm)']
['setosa' 'versicolor' 'virginica']
[5.1 3.5 1.4 0.2]
['DESCR', 'data', 'feature_names', 'target', 'target_names']

Current behaviour

$ pylint scikitlearn.py
No config file found, using default configuration
************* Module scikitlearn
C:  8, 0: Final newline missing (missing-final-newline)
C:  1, 0: Missing module docstring (missing-docstring)
C:  3, 0: Constant name "iris" doesn't conform to UPPER_CASE naming style (invalid-name)
E:  4, 6: Instance of 'tuple' has no 'feature_names' member (no-member)
E:  5, 6: Instance of 'tuple' has no 'target_names' member (no-member)
E:  6, 6: Instance of 'tuple' has no 'data' member (no-member)

Expected behavior

Pylint displaying a false positive for the above code

pylint --version output

Thanks for the issue, I can reproduce it. I'm not sure why pylint considers the return of load_iris to be a tuple instead of a Bunch object, but we could probably fix it with an astroid brain tip.

[maxkleiner]

thanx for fix

iris = datasets.load_iris()
X = iris.data
y = iris.target
class_names = iris.target_names
print(class_names)
df = pd.DataFrame(X, columns=iris.feature_names)
print(df.head())
print(df.describe())

@maxkleiner This is currently not fixed, the issue is still present.

@maxkleiner
Please use
X = iris["data"]
Y = iris["target"]
