Question

我正在尝试在具有1个NVIDIA Tesla K80 GPU的Ubuntu 16.04 Google Compute Engine实例中运行Gazebo。使用以下drivers配置GPU，这是必需的，因为我也在应用程序中使用了Tensorflow。

给出了一个类似问题的解决方案here，但是我在实现JLiviero或Jose Luis Rivero的答案方面没有任何成功。根据JLiviero的解决方案设置Xvfb之后，以详细模式运行Gazebo失败，并产生以下输出：

我在实例中使用的软件：

凉亭版本：7.14
Python版本：2.7.12
Tensorflow版本：1.10.1

如何使凉亭运行而不会崩溃？

Answer 1

看起来凉亭正试图利用X服务器。我怀疑安装一些显示环境软件包可能会有所帮助。

尝试：

sudo apt-get install gnome-core

如何在带有GPU的Google Compute Engine上运行Gazebo？
