WebOnce you have imported NumPy using >>> import numpy as np the dtypes are available as np.bool_, np.float32, etc. Advanced types, not listed above, are explored in section Structured arrays. There are 5 basic numerical types representing booleans (bool), integers (int), unsigned integers (uint) floating point (float) and complex. Web8 Apr 2024 · The dtype object that you pass in will look something like {"col1": np.int64} but that has type dict [ {"col1": type [np.int64]}], and not type dict [ {"col1": np.int64}] which is what we need in order to infer the correct type for the DataFrame.
