我正在尝试在Unity中使用compute-rhino3d的库进行开发，但是发现在不提供server的情况下无法运行。教程中只需要提供AuthToken即可。请问是”https://compute.rhino3d.com“这个云端server不能运行了吗？我必须要部署一个虚拟或本地的服务器才能够运行吗？
开发方法参考了官方给出的油管视频：https://www.youtube.com/watch?v=zUbm83ynn0Q
以及对应的.NET开发方法，同时也使用Python进行了auth token的测试，方法同样参考了官方教程视频
我在使用rhino3dm库时，没有遇到任何问题，但在尝试使用compute-rhino3d时遇到了以下问题：
- 官方教程显示，使用compute-rhino3d时，只需要提供对应的AuthToken，而server并不是必须的——我在使用Python进行尝试时，使用代码如下：
import rhino3dm
import random
import compute_rhino3d
import compute_rhino3d.Util
import compute_rhino3d.Curve
model = rhino3dm.File3dm()
compute_rhino3d.Util.authToken = "MyAuthToken"
def sample():
curves = []
for i in range(20):
pt = rhino3dm.Point3d(random.uniform(-10, 10), random.uniform(-10, 10), 0)
# print(pt)
model.Objects.AddPoint(pt)
circle = rhino3dm.Circle(pt, random.uniform(1, 4))
model.Objects.AddCircle(circle)
curve = circle.ToNurbsCurve()
curves.append(curve)
bcurves = compute_rhino3d.Curve.CreateBooleanUnion(curves)
for bcurve in bcurves:
print(bcurve)
model.Write('test.3dm', 5)
if __name__ == '__main__':
sample()
报错如下：

请问我要怎么才能快速地开始使用compute-rhino3d？如果我可以的话我希望不用自己部署服务器。
