How To Solve KeyError: u"None of [Index([..], dtype='object')] are in the [columns]"

Question

I'm trying to create a SVM model from what I found in github here , but it keeps returning this error.

Traceback (most recent call last):
  File "C:\Users\Me\Documents\#e\projects\Sign-Language-Glove-master\modeling.py", line 22, in <module>

This is my code.

import pandas as pd
dataframe= pd.read_csv("lettera.csv", delimiter=',')
df=pd.DataFrame(dataframe)

from sklearn.model_selection import train_test_split
train, test = train_test_split(df, test_size = 0.2)

train_features = train[['F1','F2','F3','F4','F5','X','Y','Z','C1','C2']]

And these are the contents of the csv file.

Answer 4

I had the same error trying to create new columns on a dataframe out of apply() results :

>>> df[["foo","bar"]] = df.apply(lambda r: ["foobar","baz"], axis=1)
"None of [Index(['foo', 'bar'], dtype='object')] are in the [columns]"

The solution was simply to use the result_type="expand" argument for apply() :

df[["foo","bar"]] = df.apply(lambda r: ["foobar","baz"], axis=1, result_type="expand")

I found this solution on this answer , which deserves upvotes.

Answer 5

Have a follow up question to this. I have a dataframe read from XLSX file. Trying to index a few columns by name and while having it in a string (derived from previous processing....)

Index(['Name', 'EmpID', 'Account', 'Project', 'StartDt', 'EndDt', 'Supervisor',
       'Billable ?', 'Onsite ?'],
      dtype='object')

Answer 6

adding index_col=0 parameter while reading a dataset
