AttributeError: 'dict' object has no attribute 'sort_values'

Question

Code is below

I am using python version 3.5

# train a random forest classifier
rf = RandomForestClassifier(n_estimators = 100, random_state = 42)
rf.fit(X_train, y_train)

# show feature importance
feature_importances_df = pd.DataFrame({"feature": features, "importance": rf.feature_importances_}).sort_values("importance", ascending = False)
feature_importances_df.head(20)

tried

feature_importances = {"feature": features, "importance": rf.feature_importances_}.sort_values("importance", ascending = False)
feature_importances_df = pd.DataFrame.from_dict(feature_importances, orient='index')

I was trying to learn sentimental analysis. got stuck with error

AttributeError: 'dict' object has no attribute 'sort_values'

move the sort_values to after the pd.DataFrame.from_dict — Quang Hoang

I am using Python 3.6.8 and pandas 0.25.1

try this

dictionary = {"a":[2,3,1,4],"b":["a","f","g","z"]}
dataFrame = pd.DataFrame.from_dict(dictionary)
dataFrame.sort_values('a',ascending=False,inplace = True)
dataFrame.reset_index(drop=True)

This will print

Hope that it helps!
