Pandas dataframe set_index KeyError: - python-3.x

Question

When importing a csv file I can't seem to set the index. I can't work out if am importing the file correctly, I am doing everything in the interpreter currently, here is what I have:
df = pd.read_csv('E:/test.vbo', sep='\t', encoding='iso-8859-1', skiprows=97)
print(df.head())
this give the following:
sats time lat long velocity heading height ...
0 [data]
1 008 144403.30 003067.21791 000031.98044 010.033 097.16 +00112.43 ...
2 008 144403.40 003067.21777 000031.98036 010.584 098.58 +00113.06 ...
3 008 144403.50 003067.21765 000031.98032 010.809 099.74 +00113.72 ...
4 008 144403.60 003067.21749 000031.98025 011.231 101.05 +00114.34 ...
5 008 144403.70 003067.21728 000031.98021 011.575 102.14 +00114.89 ...
Which is fine, however, this line:
print(df.set_index('time'))
give an error:
>>> print(df.set_index('time'))

Solved, here is the correct read_csv line:
>>> df = pd.read_csv('E:/vbox_data/P1GTR__20150922144312_0001.vbo', delim_whitespace=True, encoding='iso-8859-1', header=90)
