Compiling Deepstream 6.0 Python Bindings: pybind11.h: No such file or directory

[mfoglio]

I am trying to compile Deepstream 6.0 Python bindings:

sudo apt install -y git python-dev python3 python3-pip python3.6-dev python3.8-dev cmake g++ build-essential \
    libglib2.0-dev libglib2.0-dev-bin python-gi-dev libtool m4 autoconf automake
sudo apt-get -y install pybind11-dev

git clone https://github.com/NVIDIA-AI-IOT/deepstream_python_apps.git
cd deepstream_python_apps
git checkout v1.1.0
cd bindings
mkdir build
cd build
cmake ..
make

I encounter the error:

ubuntu@ip-x-x-x-x:~/pycharm/libs/deepstream_python_apps/bindings/build$ cmake ..

If I look for pybind11.h I can find it in:

/usr/include/pybind11/pybind11.h

Setup:

• Ubuntu 18.04
• Deepstream 6.0
• 8.0.1.6
• Tesla T4
• Drivers 470.82.00
• Cuda 11.4

please refer to deepstream_python_apps/bindings at master · NVIDIA-AI-IOT/deepstream_python_apps · GitHub and steps below if you use DS6,0GA docker -

**1.  Prerequisites
# apt install -y git python-dev python3 python3-pip python3.6-dev python3.8-dev cmake g++ build-essential \
    libglib2.0-dev libglib2.0-dev-bin python-gi-dev libtool m4 autoconf automake

 **2. Gst-python
# cd /opt/nvidia/deepstream/deepstream/sources/apps/
# git clone https://github.com/NVIDIA-AI-IOT/deepstream_python_apps.git
# cd deepstream_python_apps/
# git submodule update --init
# apt-get install --reinstall ca-certificates
# cd 3rdparty/gst-python/
# ./autogen.sh
# make
# make install

**3. install pyds
# cd deepstream_python_apps/bindings/
# mkdir build
# cd build
# cmake ..
# make
# pip3 install ./pyds-1.1.0-py3-none-linux_x86_64.whl

**4. run sample
# cd deepstream_python_apps
# mv  apps/* ./
# cd deepstream-test1/
# python3 deepstream_test_1.py ../../../../samples/streams/sample_qHD.h264

Note: autogen.sh is in folder 3rdparty/gst-python/ of the repository. ==> thanks!

git checkout v1.1.0 ==> maybe, it’s git checkout tags/v1.1.0
git submodule update --init ==> refer to Git - Submodules

Hi @mchi I guess you wanted to posted the message as a new one instead of modifying my message? :)
Do you think I should first do the checkout or the submodule update?

[mchi]

I guess you wanted to posted the message as a new one instead of modifying my message? :) ==> yes, sorry, my mistake. seems I can’t revert it now.

Do you think I should first do the checkout or the submodule update ? ==> no. just refer to the guide on deepstream_python_apps/bindings at master · NVIDIA-AI-IOT/deepstream_python_apps · GitHub , no need to checkout before submodule update

[mfoglio]

Let me rephrase my question: if I want to do a git checkout (to re-install the exact same version in the future) do you think I need to do it before the git submodule update --init or after it?

[mchi]

after git submodule update --init

Thank you! I have been able to complete the installation successfully.
