运行camera时出现错误

运行camera=ti.ui.Camera()提示出现错误
“Exception has occurred: TypeError
init() missing 1 required positional argument: ‘ptr’”
请问应该怎么解决？

Hello wxm193，
可以麻烦贴一下复现代码吗？

就是官方网站上那个“ An example of drawing 3d-lines”

我在本地用taichi v1.3.0似乎可以正常跑示例代码：

import taichi as ti

ti.init(arch=ti.cuda)

N = 10

particles_pos = ti.Vector.field(3, dtype=ti.f32, shape = N)
points_pos = ti.Vector.field(3, dtype=ti.f32, shape = N)

@ti.kernel
def init_points_pos(points : ti.template()):
    for i in range(points.shape[0]):
        points[i] = [i for j in ti.static(range(3))]

init_points_pos(particles_pos)
init_points_pos(points_pos)

window = ti.ui.Window("Test for Drawing 3d-lines", (768, 768))
canvas = window.get_canvas()
scene = ti.ui.Scene()
camera = ti.ui.Camera()
camera.position(5, 2, 2)

while window.running:
    camera.track_user_inputs(window, movement_speed=0.03, hold_key=ti.ui.RMB)
    scene.set_camera(camera)
    scene.ambient_light((0.8, 0.8, 0.8))
    scene.point_light(pos=(0.5, 1.5, 1.5), color=(1, 1, 1)) 

    scene.particles(particles_pos, color = (0.68, 0.26, 0.19), radius = 0.1)
    # Draw 3d-lines in the scene
    scene.lines(points_pos, color = (0.28, 0.68, 0.99), width = 5.0)
    canvas.scene(scene)
    window.show()

你可以检查一下你的Taichi版本嘛？

是版本问题，是我的疏忽，我原来用的是1.0.4，出现错误，1.3.0版本没问题，谢谢您！
