‘numpy.float64‘ object cannot be interpreted as an integer

能运行的代码：

import numpy as npaaa=np.linspace(0.2, 1, 9)print(aaa)

报错的代码：

import numpy as npccc=np.round((0.95 - .5) / .05)
print(ccc)iouThrs = np.linspace(0.5, 0.95, ccc + 1, endpoint=True)print(iouThrs)

原因：

np.round 函数默认返回是0位小数，但是数据类型是float64类型，不是int类型。

ccc+1这个参数需要是int类型，不是float64类型。

解决方法：

import numpy as npccc=np.round((0.95 - .5) / .05)
print(ccc)iouThrs = np.linspace(0.5, 0.95, int(ccc) + 1, endpoint=True)print(iouThrs)
