Memoryerror: Unable To Allocate Array With Shape (118, 840983) And Data Type Float64

I'm getting the following error: MemoryError: Unable to allocate array with shape (118, 840983) and data type float64 in my python code whenever I am running a python pandas.rea

Solution 1:

The MemoryError means, you file is too large to readcsv in one time, you need used the chunksize to avoid the error.

just like:

import pandas as pd
df = pd.read_csv("LANGEVIN_DATA.txt", delim_whitespace=True, chunksize=1000)

you can read the official document for more help.
