ImportError: libyaml-cpp.so.0.6: cannot open shared object file: No such file or directory

I have libyaml-cpp.so.0.7 installed. When I try to import pybuda I see the following error:

Traceback (most recent call last):
  File "/home/todd/tt-please/smoke.py", line 2, in <module>

ImportError: libyaml-cpp.so.0.6: cannot open shared object file: No such file or directory

I have 0.7 installed, is there any reason it needs to be 0.6?

Hi @tyamakawatt .

Which version of OS are you on? I'm assuming Ubuntu 22.04?

If that is the case, then yes, you need version 0.6. We have instruction in the first 5 steps for downloading the correct version of libyaml-cpp-dev based on OS: https://github.com/tenstorrent/tt-buda-demos/blob/main/first_5_steps/1_install_tt_buda.md#backend-compiler-dependencies

Hi @milank94, I am on Ubuntu 22.04. When I use the docs you pointed me to, import pybuda works now. Thanks for your help.

It looks like the docs linked in the README are out of date so I submitted a PR to update the docs to the link you sent me: #38
