error: invalid use of incomplete type 'PyFrameObject' {aka 'struct _frame'}

Hi. Unfortunately it fails to build Pangolin in the final step which is ./install_dpvo.sh. Could you please double check if your instruction is correct at the moment. Thank you. The following is a screenshot of the error report:

Hi, I got the same error. here is my solution.

• Problem

PyFrameObject was removed in python 3.11.
Python version of (dpvo) env is 3.10, while (base) env in the docker container is 3.11.
Then cmake .. in ./install_dpvo.sh selected wrong interpreter of (base).

-- Selected Python: '/root/miniconda3/bin/python3.11'. cmake --build . -t pypangolin_pip_install to use pypangolin module.

• Solution
  Downgrade python version of (base) to 3.10, and retry ./install_dpvo.sh

conda deactivate 
conda install python=3.10
conda activate dpvo

Now cmake .. successfully selected the interpreter of (dpvo), showing

-- Selected Python: '/root/miniconda3/envs/dpvo/bin/python3.10'. cmake --build . -t pypangolin_pip_install to use pypangolin module.

I could run the demo with this modification!

Thank you for the suggestion, I have also found that its being related to the version of CMAKE. Because its been rewritten in the header file. The downgrading of python env also means the downgrading of cmake version, which works for me.
