Description: TRIV2 toolchain
This is a metapackage for TRIV2 toolchain. This package installs all modules
related to the TRIV2 toolchain. The core of TRIV2 toolchain is the
tv2-compiler and it depends on ONE compiler modules. The ONE compiler
generated circle models from the TensorFlow, TensorFlow Lite and ONNX models
while supporting some optimization pass. It also supports to quantization
using auto generated random input for better quantization testing. The TRIV2
compiler takes circle models as an input and generates code optimzied for
TRIV2. This package provides the tv2-ssinfer to inference model with a TRIV2
loadable (.tvn) via TRIV2 System Service API (a.k.a. npu-engine) and the
tv2-ssprofile to profile a TRIV2 loadable via TRIV2 System Service API. This
package also provides some useful binaries such as tv2-as (an assembler) and
tv2-show (a TRIV2 loadable model reader).
This metapackage will install the latest dependent packages.
