Python APIs

Most Vitis AI advanced low-level Python APIs in module n2cube are equivalent with C++ APIs in library libn2cube. The differences between them are listed below, which are also described in the subsequent sections.

dpuGetOutputTensorAddress()

The type of return value different from C++ API.

dpuGetTensorAddress()

The type of return value different from C++ API.

dpuGetInputTensorAddress()

Not available for Python API.

dpuGetTensorData()

Available only for Python API

dpuGetOutputTensorInCHWInt8()

The type of return value different from C++ API.

dpuGetOutputTensorInCHWFP32()

The type of return value different from C++ API.

dpuGetOutputTensorInHWCInt8

The type of return value different from C++ API.

dpuGetOutputTensorInHWCFP32()

The type of return value different from C++ API.

dpuRunSoftmax()

The type of return value different from C++ API.

In addition, the feature of DPU split IO is not available for Python interface. Hence the following two APIs cannot be used by the users to deploy model with Python.

• dpuBindInputTensorBaseAddress()
• dpuBindOutputTensorBaseAddress()
