TypeError:\uuuu init\uuuuuu（）为参数“center”获取了多个值

Question

我对这一点还不熟悉，我试着查看类似的错误，但我不确定为什么“中心”会成为图形中心的目标

import yt

ds = yt.load("puredef_hdf5_chk_000000")
p = yt.ProjectionPlot(ds,'particle_postion_x', 'particle_postion_y',['particle_dens'], center='m', width=(20, 'Mpc'))
p.annotate_particles((20, 'Mpc'))
p.save()

其输出为：

TypeError: __init__() got multiple values for argument 'center'

函数yt.ProjectionPlot包含3个参数，其余为带关键字的可选参数。您正在使用4个参数，因此是1对多（['particle_dens']）。这可能还需要一个关键字参数
