Description
If you try to read a csv file into a dataframe, and the csv file has just the header and no rows, it throws 'object of type 'bool' has no len()'. This issue does not seem to exist in 0.16.1.
The sample csv file is blank:
id,strategyId,symbol,side,target,time,reason,epochTime
Code that causes the issue:
import pandas as pd
df = pd.read_table(path_to_csv, sep=',', index_col=False)
Code that does not have the issue:
import pandas as pd
df = pd.read_table(path_to_csv, sep=',')
