Specifying dtype float32 with pandas.read_csv on pandas 0.10.1

Question

I\'m attempting to read a simple space-separated file with pandas read_csv method. However, pandas doesn\'t seem to be obeying my dtype argument.

Answer 1

In [22]: df.a.dtype = pd.np.float32

In [23]: df.a.dtype
Out[23]: dtype('float32')

the above works fine for me under pandas 0.10.1
