Notes

Kernel configuration arguments set by this class:

TODO

KTYPE = 'ck'¶

FILE_EXT = '.bc'¶

properties¶

prepare_input_data(input_data: pandas.DataFrame) → list[pandas.DataFrame]¶: Prepare an accessor that will provide input data for the kernel.

write_input_data(fobj_or_str, input_data: pandas.DataFrame)¶: Write input data.

_write_kernel(setup_file, input_file, kernel_file, append=False)¶

Setup the command to create a “CK” kernel using the external tool “msopck”.

Parameters:

setup_file (str) – Setup file containing kernel creation properties (see “msopck”).
input_file (str) – Input data file to create kernel from.
kernel_file (str) – Kernel filename to create.
append (bool, optional) – Not supported by msopck (auto-appends). Public wrappers methods add support for not appending.

Returns:

List of subprocess commands and arguments.

Return type:

list of str
