class ToNumber : public mindspore::dataset::TensorTransform 

Convert every element in a string tensor to a number. Strings are cast according to the rules specified in the following links: https://en.cppreference.com/w/cpp/string/basic_string/stof, https://en.cppreference.com/w/cpp/string/basic_string/stoul, except that any strings which represent negative numbers cannot be cast to an unsigned integer type.

Public Functions

explicit ToNumber(mindspore::DataType data_type)

Constructor.

参数

data_type – [in] mindspore::DataType of the tensor to be cast to. Must be a numeric type, excluding bool.

样例

/* Define operations */
auto to_number_op = text::ToNumber(mindspore::DataType::kNumberTypeInt8);

/* dataset is an instance of Dataset object */
dataset = dataset->Map({to_number_op},   // operations
                       {"text"});        // input columns

~ToNumber() override = default: Destructor.
