why does my index begins from second row?

Question

results=pd.DataFrame({"Picture":filenames,"predictions":predictions})
results.to_csv("/home/udas/scratch/projekt01/results.csv",index=False,header=None)

kf= pd.read_csv('/home/udas/scratch/projekt01/results.csv')

print(kf.head())

Why does my index begins at second row?

Can anyone help to solve it?

Answer 1

Here you save without header: results.to_csv("/home/udas/scratch/projekt01/results.csv",index=False,header=None)

But here you read with assumptation that header exists, so first row of data is used for header:

kf= pd.read_csv('/home/udas/scratch/projekt01/results.csv')

So two options, either :

A) results.to_csv("/home/udas/scratch/projekt01/results.csv",index=False) or:

B) kf= pd.read_csv('/home/udas/scratch/projekt01/results.csv', header=0)
