Use theto_numeric()Function to Convert Object to Float in Pandas The Pandasto_numeric()functioncan be used to convert a list, a series, an array, or a tuple to a numeric datatype, which means signed, or unsignedintandfloattype. It also has theerrorsparameter to raise exceptions. ...
To convert floats to integers in Pandas, you can use the astype() function. This function allows you to convert a column or series of a DataFrame to a different data type. For example, suppose you have a DataFrame df with a column 'col' that contains floating point values: import pandas...

你可以根据需要进一步处理这些NaN值。总结:解决“TypeError: can’t convert np.ndarray of type numpy.object_”的报错问题需要确保数组中数据类型的一致性。你可以使用NumPy的astype()方法、Python内置函数或pandas库来进行数据类型的转换。根据具体情况选择合适的方法,以避免在处理NumPy数组时出现类型不匹配的问题。
That is why without conversion, pandas results in object dtype. df_with_numpy_values = pd.DataFrame( { "col_int": [np.int64(1), np.int64(2)], "col_float": [np.float64(1.5), np.float64(2.5)], "col_bool": [np.bool_(True), np.bool_(False)], "col_str": [np.str_("a"...
