虚拟机Ubuntu16.04系统安装PyBullet并实现成功运行官方给出的示例
|
虚拟机软件：VirtualBox 虚拟操作系统版本：Ubuntu16.04LTS 安装参考：https://github.com/bulletphysics/bullet3/blob/master/README.md
安装非常简单，已经顺利安装pybullet-3.2.5。下面运行一下，给定的三个样例吧。 测试官方例子 解决报错ImportError: No module named 'gym' python3 -m pybullet_envs.examples.enjoy_TF_AntBulletEnv_v0_2017may
报错ImportError: No module named 'gym'的解决方案，安装gym，输入命令 pip3 install -i https://pypi.tuna.tsinghua.edu.cn/simple gym再次运行 python3 -m pybullet_envs.examples.enjoy_TF_HumanoidFlagrunHarderBulletEnv_v1_2017jul很显然，报错ImportError: No module named 'gym'的问题已经解决。但是，发现出现了新的报错问题： Failed to create GL 3.3 context ... using old-style GLX context error: GLSL 1.50 is not supported. Supported versions are: 1.10, 1.20，and1.00 ES 解决报错 error: GLSL 1.50 is not supported. Supported versions are: 1.10, 1.20，and1.00 ES
解决方案： 关闭虚拟机，点击【显示】-->【屏幕】，取消勾选硬件加速：启用3D加速。
打开虚拟机，再次输入 python3 -m pybullet_envs.examples.enjoy_TF_HumanoidFlagrunHarderBulletEnv_v1_2017jul
成功啦！再来看下一个 python3 -m pybullet_envs.examples.enjoy_TF_AntBulletEnv_v0_2017may
同样成功！继续 python3 -m pybullet_envs.deep_mimic.testrl --arg_file run_humanoid3d_backflip_args.txt
报错ImportError: No module named 'tensorflow'，解决方案，安装tensorflow，输入 pip3 install tensorflow结果是 zlj@zlj-VirtualBox:~$ pip3 --default-timeout=1000 install matplotlib DEPRECATION: Python 3.5 reached the end of its life on September 13th, 2020.

可以看到已经成功安装enum34-1.1.10，符合>=1.0.4的要求。此时仍存在报错（在预想范围，第二步会重新下载或升级futures） ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts. grpcio 1.41.1 requires futures>=2.2.0, which is not installed. 第二步，安装futures，输入 pip3 install futures
我们可以推知，此时应该已经满足TensorFlow所有的版本要求了，我们测试一下，果然如此 zlj@zlj-VirtualBox:~$ pip3 install tensorflow DEPRECATION: Python 3.5 reached the end of its life on September 13th, 2020.

附录（虚拟机启用3D加速时）： 尝试查询OpenGL版本，输入 glxinfo | grep "OpenGL version"显示：程序“glxinfo”尚未安装。 您可以使用以下命令安装：sudo apt install mesa-utils 按照提示，进行安装，输入 sudo apt install mesa-utils再次查询，输入 glxinfo | grep "OpenGL version"
查询的结果是OpenGL version string: 2.1 Mesa 18.0.5。 |
