{'test_vector': array([1., 2., 3.])} This consists on two steps: 1.First, the file is parsed using the function parse_file(). This provides a literal description of the file contents as a hierarchy of Python objects representing the basic R objects. This step is unambiguous and always the same. 2.Then, each object must be converted to an appropriate Python object. In this step there are ...

Inputting data with tf.convert_to_tensor() is convenient, but doesn’t scale. Use tf.placeholder variables (dummy nodes that provide entry points for data to computational graph).

is a need, the user can simply apply the Python built-in function dict to convert such a list to a Python dictionary. An R data frame is a table-like data structure, in which rows represent records and columns represent elements in each record. Di erent columns can be of di erent data types. RPy can only convert data frames into Python lists with each column in the data frame as an element ...
