How to read file with space separated values in pandas

I try to read the file into pandas. The file has values separated by space, but with different number of spaces I tried: pd.read_csv('file.csv', delimiter=' ') but it doesn't work
Add delim_whitespace=True argument, it's faster than regex. Note however that after pandas 2.2.0 this is deprecated and it's better to use sep="\s+"
