TVM Plugin🔗

The TVM plugin for vAccel implements image inference vAccel operations with TVM.

Supported operations🔗

Image classification

Installing TVM C/C++ API files🔗

You can find instructions on how to install the required files on the Build and Install TVM page. The rest of this guide assumes TVM is installed at /opt/tvm and its' libraries are at /opt/tvm/build.

Installing the plugin🔗

You can get the latest TVM plugin binary release from the Releases page of the vAccel repository. Releases include binaries for x86_64/aarch64 Ubuntu-based systems.

TAR🔗

To install the TAR binary package of the latest TVM plugin release:

x86ARM (64-bit)

wget https://github.com/nubificus/vaccel/releases/download/v0.8.0/vaccel-tvm_0.2.0+vaccel.0.8.0_x86_64.tar.gz
# Replace '/usr/local' below with the desired installation prefix
tar xfv vaccel-tvm_0.2.0+vaccel.0.8.0_x86_64.tar.gz --strip-components=2 -C /usr/local
# Update pkg-config files with the correct prefix
find /usr/local -name "vaccel-tvm.pc" -exec sed -i 's:^\(prefix=\).*:\1/usr/local:g' {} \;

wget https://github.com/nubificus/vaccel/releases/download/v0.8.0/vaccel-tvm_0.2.0+vaccel.0.8.0_aarch64.tar.gz
# Replace '/usr/local' below with the desired installation prefix
tar xfv vaccel-tvm_0.2.0+vaccel.0.8.0_aarch64.tar.gz --strip-components=2 -C /usr/local
# Update pkg-config files with the correct prefix
find /usr/local -name "vaccel-tvm.pc" -exec sed -i 's:^\(prefix=\).*:\1/usr/local:g' {} \;

Latest artifacts🔗

You can also find prebuilt artifacts of the latest TVM plugin revision at:

x86ARM (64-bit)

# TAR
https://s3.nbfc.io/nbfc-assets/github/vaccel/plugins/tvm/rev/main/x86_64/release/vaccel-tvm_latest_x86_64.tar.gz

# TAR

Usage🔗

To specify TVM plugin as the selected plugin for vAccel execution:

export VACCEL_PLUGINS=libvaccel-tvm.so

Ensure TVM, vAccel and the TVM plugin libraries are in the library search paths before trying to use the plugin.

Running an example🔗

Export the necessary variables:

export LD_LIBRARY_PATH=/opt/tvm/build
export VACCEL_PLUGINS=libvaccel-tvm.so
# Optionally, for verbose output
export VACCEL_LOG_LEVEL=4

Assuming vAccel is installed at /usr/local, you can run an image classification with a ResNet model from https://s3.nbfc.io/models/tvm/x86_64/resnet18-v2-7.so with:
