Class DTypePromotionError

Namespace

NumSharp

Assembly

NumSharp.dll

numpy.exceptions.DTypePromotionError — raised when two (or more) DTypes have no common DType, i.e. np.promote_types / np.result_type cannot find a dtype that can hold every input (NEP 42's common_dtype protocol returned NotImplemented in both directions).

Remarks

Derives from TypeError exactly as NumPy's does (DTypePromotionError(TypeError)), so a catch (TypeError) written for NumPy 1.x code keeps working. The two message shapes are NumPy's verbatim texts from common_dtype.c:

• The DTypes <class 'numpy.dtypes.DateTime64DType'> and <class 'numpy.dtypes.Float64DType'> do not have a common DType. For example they cannot be stored in a single array unless the dtype is `object`. (the pairwise PyArray_CommonDType)
• The DType %S could not be promoted by %S. This means that no common DType exists for the given inputs. For example they cannot be stored in a single array unless the dtype is `object`. The full list of DTypes is: (%S, …) (the sequence reduction PyArray_PromoteDTypeSequence)
