Remove go-vncdriver #11

Closed scriptingislife closed 7 years ago

scriptingislife commented 7 years ago

I am trying to set up Universe with OpenAI but am having trouble with go-vncdriver. When I run the given test program, named trial.py in this case, I'm given this error: Traceback (most recent call last): File "trial.py", line 11, in <module> env.render() File "/usr/local/lib/python2.7/dist-packages/gym/core.py", line 192, in render return self._render(mode=mode, close=close) File "/usr/local/lib/python2.7/dist-packages/gym/core.py", line 342, in _render return self.env.render(mode, close) File "/usr/local/lib/python2.7/dist-packages/gym/core.py", line 192, in render return self._render(mode=mode, close=close) File "/home/nathaniel/Documents/machinelearning/universe/universe/wrappers/render.py", line 49, in _render return self.env.render(mode=mode, *args, **kwargs) File "/usr/local/lib/python2.7/dist-packages/gym/core.py", line 192, in render return self._render(mode=mode, close=close) File "/usr/local/lib/python2.7/dist-packages/gym/core.py", line 342, in _render return self.env.render(mode, close) File "/usr/local/lib/python2.7/dist-packages/gym/core.py", line 192, in render return self._render(mode=mode, close=close) File "/home/nathaniel/Documents/machinelearning/universe/universe/envs/vnc_env.py", line 533, in _render self.vnc_session.render(self.connection_names[0]) go_vncdriver.Error: /tmp/pip-build-y6uWFh/go-vncdriver/.build/src/github.com/openai/go-vncdriver/main.go:387: go_vncdriver was installed without OpenGL support. See https://github.com/openai/go-vncdriver for details on how debug.

I have now installed the correct dependencies and gotten it to build with OpenGL, but the program is still running without it. Is there a way to remove go-vcndriver and do a clean install?

My usual trick is to entirely remove the code: i.e. find the path with python -c "import go_vncdriver; print(go_vncdriver.__file__)" and then rm -rf </path/...>. You can then try to import go_vncdriver again and make sure it fails.

Thanks! That worked, but now after running ./build.sh again I get ImportError: No module named go_vncdriver even though when I run pip install go_vncdriver I get Requirement already satisfied: go_vncdriver in /usr/local/lib/python2.7/dist-packages

So two things you can do:

  1. pip install --no-cache-dir --ignore-installed --upgrade go_vncdriver (basically the hammer approach)
  2. pip install -e /path/to/go_vncdriver — use your existing on-disk checkout

It works! Thank you very much for your help. I think this is my first time installing a program completely from git.

I ran into same issue yesterday, submitted PR https://github.com/openai/go-vncdriver/pull/8

This is solved for @becksteadn I think the new build instructions in #8 will mostly keep people from stumbling into this issue in the future.
