Prevent pandas from reading "NA" as NaN : <p>The .csv-file I'm reading from contains cells with the value "NA". Pandas automatically converts these into NaN, which I don't want. I'm aware of the <code>keep_default_na=False</code> parameter, but that changes the dtype of the columns to <code>object</code> which means <code>pd.get_dummies</code> doesn't work correctly.</p>

<p>Is there any way to prevent pandas from reading "NA" as NaN without changing the dtype?</p>
