Can memmap pandas series. What about a dataframe?

Question

It seems that I can memmap the underlying data for a python series by creating a mmap\'d ndarray and using it to initialize the Series.

If you change your DataFrame constructor to add the parameter copy=False you will have the behavior you want. https://pandas.pydata.org/pandas-docs/stable/generated/pandas.DataFrame.html

Edit: Also, you want to use the underlying ndarray (rather than the pandas series).
