各位老师好
我有个很简单的问题，就是在屏幕上画一个点。用的是gui.circles()
但是总是出现如下报错
Original exception was:
Traceback (most recent call last):
File "d:\codes\taichi_run\taichiCourse\myHomework\拉普拉斯方程生成网格\laplaceMesh\laplaceMesh.py", line 34, in <module>
draw()
File "d:\codes\taichi_run\taichiCourse\myHomework\拉普拉斯方程生成网格\laplaceMesh\laplaceMesh.py", line 26, in draw
gui.circles(nodes_np,
File "C:\ProgramData\Miniconda3\lib\site-packages\taichi\misc\gui.py", line 323, in circles
assert pos.shape[2] == 1
AssertionError
我的程序的代码大致是这样的：
nodes = ti.Vector.field(2, ti.f64, (numNodes, numNodes))
@ti.kernel
def init():
nodes[0, 0].x =0.5
nodes[0, 0].y =0.5
def draw():
gui = ti.GUI("laplaceMesh",
background_color=0xFFFFFF,
)
nodes_np = nodes.to_numpy()
while ti.GUI.running:
gui.circles(nodes_np,
color=0x000000
radius=1.0)
gui.show()
if __name__ == "__main__":
init()
draw()
