Pre-requisites

  • Raspberry Pi 4B or Raspberry Pi 400

  • Raspberry Pi OS (64-bit)

If you have requirements for running on alternative hardware and/or OS, please contact us for assistance.

Dependencies

The following steps will allow you to install the necessary dependencies for running the inference examples on a Raspberry Pi:

# CMake and OpenCV are required
sudo apt install libopencv-dev cmake

# Build and install a compatible version of TVM runtime
mkdir ~/src
cd ~/src
git clone https://github.com/apache/tvm.git tvm
cd tvm
git checkout 1970223
git submodule init
git submodule update
mkdir build
cp cmake/config.cmake build
cd build
cmake ..

# You will only need the runtime components
make runtime

# Set TVM_HOME to point to the tvm directory
# If you installed it in another location, update this
# command accordingly.

echo 'export TVM_HOME=~/src/tvm/' >> ~/.bashrc

# IMPORTANT: Now logout/login for changes to take effect.
CODE

Next Steps

You should now be able to run the C++ inference examples from Step Four on your Raspberry Pi.
