"Uses an index mapping to convert a dictionary to an array.

" Given a dictionary, each key is looked up in the vocabulary attribute corresponding to"

" used to index the output 1-D tensor 'Y' and insert into it the value found in the dictionary 'X'.
"
" The key type of the input map must correspond to the element type of the defined vocabulary attribute."
" Therefore, the output array will be equal in length to the index mapping vector parameter."
" All keys in the input dictionary must be present in the index mapping vector."
" For each item in the input dictionary, insert its value in the output array."
" Any keys not present in the input dictionary, will be zero in the output array.

mlonnx.LabelEncoder (MLONNXLabelEncoderOp)
ONNX LabelEncoder operation
"Maps each element in the input tensor to another value.
"
" The mapping is determined by the two parallel attributes, 'keys_' and"
" 'values_' attribute. The i-th value in the specified 'keys_' attribute"
" would be mapped to the i-th value in the specified 'values_' attribute. It"
" implies that input's element type and the element type of the specified"
" 'keys_' should be identical while the output type is identical to the"
" specified 'values_' attribute. If an input element can not be found in the"
" specified 'keys_' attribute, the 'default_' that matches the specified"
" 'values_' attribute may be used as its output value.
"
" Let's consider an example which maps a string tensor to an integer tensor."
" Assume and 'keys_strings' is ["Amy", "Sally"], 'values_int64s' is [5, 6],"
" and 'default_int64' is '-1'. The input ["Dori", "Amy", "Amy", "Sally","
" "Sally"] would be mapped to [-1, 5, 5, 6, 6].
"
" Since this operator is an one-to-one mapping, its input and output shapes"
" are the same. Notice that only one of 'keys_'/'values_' can be set.
"
" For key look-up, bit-wise comparison is used so even a float NaN can be"
" mapped to a value in 'values_' attribute.
