pub struct CPUContext { /* private fields */ }
Expand description

| The CPU Context, representing the bare | minimum of what a Context class in Caffe2 | should implement. | | // TODO modify docs | | See operator.h, especially Operator, | for how Context are used in actual operator | implementations that are associated | with specific devices. | | In general, the Context class is passed | in as a template argument, and the operator | can use the functions defined in the | context to execute whatever computation | it has. |
