This don't work:

sudo apt update
sudo apt install graphviz
pip install terravision
/home/anlexn/.pyenv/versions/3.12.10/lib/python3.12/site-packages/terravision.py draw --source . --format svg

This terravision can not use 'neato' layout engine. architecture diagram is also not rendered correctly.

This don't work too:

git clone https://github.com/patrickchugh/terravision.git
pushd terravision
pip install -r requirements.txt
cp hcl2/hcl2.lark /home/anlexn/.pyenv/versions/3.12.10/lib/python3.12/site-packages/hcl2/hcl2.lark

In the ~\.pyenv\versions\3.12.10\lib\python3.12\site-packages\graphviz\backend\rendering.py:

I also change

    cmd = dot_command.command(engine, format,
                              renderer=renderer,
                              formatter=formatter,
                              neato_no_op=neato_no_op)

to

    cmd = dot_command.command('dot', format,
                              renderer=renderer,
                              formatter=formatter,

Hi thanks for this can you also try without the format parameters just to create a . PNG? Does that work ?

Hello, I just tested out terravision on a fresh Ubuntu VM and I am unable to reproduce your error. Since this is the first time I am hearing abut this particular issue, I am assuming it is something to do with your Python environment or local graphviz installation.

Please delete and re-install graphviz from official sources, then try to use a virtual environment to run it again.

You can also try to use pipx to install it with the commnad pipx install terravision - this will create a virtual environment to run terravision in an isolated space. You do not need to copy any files like you are doing:
cp hcl2/hcl2.lark /home/anlexn/.pyenv/versions/3.12.10/lib/python3.12/site-packages/hcl2/hcl2.lark

Also, when you are trying to open SVG files do not use Visual Studio but some other tool like Inkscape since VSCode doesn't have a good viewer for it and incorrectly renders the files.

Hope this helps.

@patrickchugh Thank you for your reply, you are my friend!

PNG don't work too.

pip install terravision also install python's graphviz. how do you install grahphviz?

Can you generate architecture diagram?

Yes works for me and others, you are the only one to report this. You may have an older version or corrupted version of graphviz installed in some other folder

Graphviz python library is different from Graphviz dot executable. Graphviz in python just calls those binary executable files, so you need to download graphviz binaries from the official website first https://graphviz.org/download/

I would suggest you to manually uninstall any previous graphviz executable files like dot and neato by searching in your path, and any python package called graphviz. Then try again using

pipx install terravision
#pipx is different from pip

Hope this helps

Sorry but GCP support has not been implemented. Have you tried Azure/AWS yet ? @anlexN Please wait until core support for GCP is ready. I will close the case for now.

@patrickchugh Thank you. How many GCP core services do terravision support now?

Top 20-25 services. Try it out on your TF code and if anything doesn't look right or is not showing up let me know and I'll prioritise those service handlers. @anlexN

You can also now run in docker or via GitHub actions now so you don't have to worry about dependencies anymore. @anlexN
