1) 我构建了可视化工具，但无法启动它。这是我看到的：

(base) Taos-MacBook-Pro:drake taosun$ bazel build //tools:drake_visualizer //manipulation/util:geometry_inspector
INFO: Analyzed 2 targets (0 packages loaded, 0 targets configured).
INFO: Found 2 targets...
INFO: Elapsed time: 0.988s, Critical Path: 0.01s
INFO: 0 processes.
INFO: Build completed successfully, 1 total action

但是当我尝试启动它时，它不起作用：

(base) Taos-MacBook-Pro:drake taosun$ ./bazel-bin/tools/drake_visualizer
Traceback (most recent call last):
  File "/usr/local/opt/vtk@8.2/lib/python3.7/site-packages/vtkmodules/vtkIOAMR.py", line 5, in <module>
    from .vtkIOAMRPython import *
ImportError: dlopen(/usr/local/opt/vtk@8.2/lib/python3.7/site-packages/vtkmodules/vtkIOAMRPython.so, 2): Library not loaded: /usr/local/opt/hdf5/lib/libhdf5.103.dylib
  Referenced from: /usr/local/opt/vtk@8.2/lib/libvtkIOAMR-8.2.1.dylib
  Reason: image not found

在处理上述异常的过程中，又出现了一个异常：

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/private/var/tmp/_bazel_taosun/faebfa4431921ca82cfb8e7cf6a74cad/external/drake_visualizer/lib/python3.7/site-packages/director/drakevisualizerapp.py", line 3, in <module>

    from vtkIOAMRPython import *
ModuleNotFoundError: No module named 'vtkIOAMRPython'

2）我也尝试了python绑定。cmake 和 make 成功完成。但是，当我尝试导入 pydrake 时，出现以下错误：

(base) Taos-MacBook-Pro:GitHub taosun$ cd drake-build
(base) Taos-MacBook-Pro:drake-build taosun$ python3 -c 'import pydrake; print(pydrake.__file__)'
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/opt/drake/lib/python3.7/site-packages/pydrake/__init__.py", line 41, in <module>
    from . import common
  File "/opt/drake/lib/python3.7/site-packages/pydrake/common/__init__.py", line 1, in <module>
    from ._module_py import *
ImportError: dlopen(/opt/drake/lib/python3.7/site-packages/pydrake/common/_module_py.so, 2): Symbol not found: _PyThread_tss_alloc
  Referenced from: /opt/drake/lib/python3.7/site-packages/pydrake/common/_module_py.so
  Expected in: flat namespace
 in /opt/drake/lib/python3.7/site-packages/pydrake/common/_module_py.so

对于以上两个问题，我怀疑是不是因为我设置不$PYTHONPATH正确。这是我现在设置的

(base) Taos-MacBook-Pro:drake-build taosun$ echo $PYTHONPATH
/opt/drake/lib/python3.7/site-packages

感谢您的帮助！

对于 VTK 错误，请尝试--define="-DUSE_SYSTEM_VTK=OFF"在构建命令的末尾添加。

bazel build //tools:drake_visualizer //manipulation/util:geometry_inspector --define="-DUSE_SYSTEM_VTK=OFF"`
