Manual Installation

The manual installation of TAPPAS requires preparation, Hailo's recommended method is to begin with Hailo SW Suite or Pre-built Docker image. This guide will instruct how to install the required components manually.

Note

Only Ubuntu 20.04 and 22.04 are supported

Hailort Installation

First HailoRT + HailoRT PCIe driver, needs to be installed. Follow the HailoRT installation guide for further instructions. After the installation, confirm that HailoRT is working correctly.

Preparations

Download from Hailo developer zone tappas_VERSION_linux_installer.zip.

x86

Unzip tappas_VERSION_linux_installer.zip

unzip tappas_VERSION_linux_installer.zip

Non-x86

  1. Unzip TAPPAS and clone HailoRT sources

    unzip tappas_VERSION_linux_installer.zip

  2. Change the directory to TAPPAS, and create a directory named hailort and clone HailoRT sources

    cd `tappas_VERSION`
mkdir hailort
git clone https://github.com/hailo-ai/hailort.git hailort/sources

Note

In some cases, HailoRT (which is installed via TAPPAS) is not the latest version, while the driver, which was installed before HailoRT and TAPPAS - has a different version. In these cases, this error will occur:

"Could not find a configuration file for package "HailoRT" that exactly matches requested version."

Meaning, HailoRT library and driver installed versions are mismatched - while they are required to be fully identical.

In such a case - re-install the driver version which is compatible to your installed HailoRT version.

Required Packages

The following APT packages need to be installed, using the command below:

  • ffmpeg
  • x11-utils
  • python3 (pip and setuptools).
  • python3-virtualenv
  • python-gi-dev
  • libgirepository1.0-dev
  • gcc-12 and g++-12
  • cmake
  • libzmq3-dev
  • git
  • rsync

To install the above packages, run the following command:

sudo apt-get install -y rsync ffmpeg x11-utils python3-dev python3-pip python3-setuptools python3-virtualenv python-gi-dev libgirepository1.0-dev gcc-12 g++-12 cmake git libzmq3-dev

The following packages are required as well, and their installation instructions can be viewed from the links below:

In case any requirements are missing, a requirements table will be printed when calling manual installation.

OpenCV Installation

To install OpenCV, run the following commands:

sudo apt-get install -y libopencv-dev python3-opencv

To check your OpenCV version, run the following command:

# To check the OpenCV version installed
pkg-config --modversion opencv4

Tip

If you are running on an old OS the apt-get version might be too old (You will be notified on the next steps), you can install OpenCV manually as shown below.

Opencv compilation from source

# Download Opencv and unzip
wget https://github.com/opencv/opencv/archive/4.5.2.zip
unzip 4.5.2.zip

# cd and make build dir
cd opencv-4.5.2
mkdir build
cd build

# Make and install
cmake -DOPENCV_GENERATE_PKGCONFIG=ON \
    -DBUILD_LIST=core,imgproc,imgcodecs,calib3d,features2d,flann \
    -DCMAKE_BUILD_TYPE=RELEASE \

num_cores_to_use=$(($(nproc)/2))
make -j$num_cores_to_use
sudo make install

# Update the linker
sudo ldconfig

GStreamer Installation

Run the following command to install GStreamer:

sudo apt-get install -y libcairo2-dev libgirepository1.0-dev libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev libgstreamer-plugins-bad1.0-dev gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly gstreamer1.0-libav gstreamer1.0-tools gstreamer1.0-x gstreamer1.0-alsa gstreamer1.0-gl gstreamer1.0-gtk3 gstreamer1.0-qt5 gstreamer1.0-pulseaudio gcc-12 g++-12 python-gi-dev

Please refer to: GStreamer official installation guide for more details

PyGobject Installation

Run the following command to install PyGobject:

sudo apt install python3-gi python3-gi-cairo gir1.2-gtk-3.0

Please refer to: PyGobject official installation guide for more details

TAPPAS Installation

On most platforms (such as x86-based platforms), run:

./install.sh --skip-hailort

and then, Make sure that HailoRT works

Raspberry Pi 4 has its own set of example applications, so the installation command on this platform is slightly different:

./install.sh --skip-hailort --target-platform rpi

and then, return to the Raspberry Pi section

On Rockchip, run:

./install.sh --skip-hailort --target-platform rockchip

and then, return to the Rockchip section.

Upgrade TAPPAS

To Upgrade TAPPAS, first clean the GStreamer cache

rm -rf ~/.cache/gstreamer-1.0/

Remove old libgsthailotools.so

rm /usr/lib/$(uname -m)-linux-gnu/gstreamer-1.0/libgsthailotools.so

and then, TAPPAS installation section

Troubleshooting

Cannot allocate memory in static TLS block

In some scenarios (especially aarch64), this warning might occur:

(gst-plugin-scanner:15): GStreamer-WARNING **: 13:58:20.557: Failed to load plugin '/usr/lib/aarch64-linux-gnu/gstreamer-1.0/libgstlibav.so': /lib/aarch64-linux-gnu/libgomp.so.1: cannot allocate memory in static TLS block

The solution is to export an environment variable:

export LD_PRELOAD=/usr/lib/aarch64-linux-gnu/libgomp.so.1

PCIe descriptor page size error

If you encounter the following error: (actual page size might vary)

[HailoRT] [error] CHECK_AS_EXPECTED failed - max_desc_page_size given 16384 is bigger than hw max desc page size 4096"

Some hosts doesn't support certain PCIe descriptor page size. in order to overcome this issue add the text below to /etc/modprobe.d/hailo_pci.conf (create the file if it doesn't exist)

options hailo_pci force_desc_page_size=4096
# you can do this by running the following command:
echo 'options hailo_pci force_desc_page_size=4096' >> /etc/modprobe.d/hailo_pci.conf

Reboot the machine for this change to take effect. You can also reload the driver without rebooting by running the following commands:

modprobe -r hailo_pci
modprobe hailo_pci
