read_csv#

Read a CSV file into a tensor

Note

This function requires the optional MATX_ENABLE_FILEIO compile flag

template<typename TensorType>
void matx::io::read_csv(TensorType &t, const std::string fname, const std::string delimiter, bool skip_header = true)#

Read a CSV file into a tensor view.

CSVs are currently read in using the Python interpreter through pybind11. This has a startup performance hit, but CSV reading is intended to be a slow-path function, so this is not a critical component to speed up. Currently 1D and 2D tensors are supported only.

Template Parameters:

TensorType – Data type of tensor

Parameters:

  • t – Tensor to read data into

  • fname – File path of .csv file

  • delimiter – Delimiter to use for CSV file

  • skip_header – Skip the header row of the CSV file, default as true.

Examples#

io::read_csv(this->Av, this->small_csv, ",");
