Might it be a problem of paths? I am not expert of linux, I just use it mainly copying and pasting instructions. In acados_template instructions it says:
“Notice that, if you want to run the examples from a location that differs from ‘<acados_root>/interfaces/acados_template’ or you want the generated Makefile to refer to a specific path (e.g. when cross-compiling or compiling from a location different from the one where you generate the C code), you will have to adapt ‘ocp.acados_include_path’ and ‘ocp.acados_lib_path’ accordingly in the generating Python code.”
I don’t know what it means but I ran the example not from <acados_root>/interfaces/acados_template.
I think there could be something wrong with the HPIPM & BLASFEO targets.
Can you try the following, namely recompiling with GENERIC and running a C example:
cd <acados_dir>
rm build/* -rf
cd build
cmake .. -DACADOS_WITH_QPOASES=ON -DACADOS_EXAMPLES=ON -DHPIPM_TARGET=GENERIC -DBLASFEO_TARGET=GENERIC
make -j4
make install -j4
# run a C example, e.g.:
./examples/c/sim_wt_model_nx6
If that works, also try the Python example.
This is outdated. I will update the instructions soon.
Recompiling as I suggested should have compiled the examples into <acados_root>/build/examples/c.
you can just execute them, no need to compile them again…
It would be great to find what went wrong with the automatic target…
Maybe you can run the cmake without the Target flags again and paste the output somewhere.
I installed texlive-base but I got the same error
“PermissionError: [Errno 13] Permission denied: ‘latex’”
So I did as you suggested and finally everything worked out perfectly
I made a fresh installation of acados in a fresh Ubuntu 19.04 virtual machine using atomatic targets. At the end I got the same error as before. So it’s sistematic. I have all the outputs of the installation but I don’t know how to paste it here.
I installed texlive_full, ran minimal_example_ocp.py with the default settings (no latexify=False) and it completed successfully with the matplotlib plot displayed.
I succeeded in running acados examples within PyCharm.
I created a dedicated environement in anaconda and launched PyCharm from there.
I then created a project in PyCharm that I called Acados and selected as python interpreter Python3.7 from anaconda folder.
Doing this linked also acado_template as the installed packages seen by PyCharm.
I then opened home/walter/acados/examples/acados_python/getting_started/minimal_example_ocp.py and ran it without problems.
