这东西真的是一个巨坑,好像在服务器上训练有时候会报这个错误,可以在报错的目录下(我的目录为:/MIP/.local/lib/python3.8/site-packages/nms)新建一个cpu_nms.py文件,加下如下代码:
import numpy as np
def mymax(a, b):
return a if a >= b else b
def mymin(a, b):
return a if a <= b else b
def cpu_nms(dets, thresh):
x1 = dets[:, 0]
y1 = dets[:, 1]
x2 = dets[:, 2]
y2 = dets[:, 3]
scores = dets[:, 4]
areas = (x2 - x1 + 1) * (y2 - y1 + 1)
order = scores.argsort()[::-1]
ndets = dets.shape[0]
suppressed = np.zeros((ndets), dtype=np.int)
keep = []
for _i in range(ndets):
i = order[_i]
if suppressed[i] == 1:
continue
keep.append(i)
ix1 = x1[i]
iy1 = y1[i]
ix2 = x2[i]
iy2 = y2[i]
iarea = areas[i]
for _j in range(_i + 1, ndets):
j = order[_j]
if suppressed[i] == 1:
continue
xx1 = mymax(ix1, x1[j])
yy1 = mymax(iy1, y1[j])
xx2 = mymin(ix2, x2[j])
yy2 = mymin(iy2, y2[j])
w = mymax(0.0, xx2 - xx1 + 1)
h = mymax(0.0, yy2 - yy1 + 1)
inter = w * h
ovr = inter / (iarea + areas[j] - inter)
if ovr >= thresh:
suppressed[j] = 1
return keep
这样可以解决No module named 'nms.cpu_nms'这个错误,但是我跑的代码在解决这个错误之后,又报了一个新的错误No module named 'nms.gpu_nms',在网上没有找到gpu_nms.py替换内容。
后来偶然发现,也许不一定是这个问题,但是我根据下面的方式解决了这个问题,下面是本人的代码目录,讲原程序的# from dataset.dataset_lits_val import Val_Dataset注释掉,改成下面这种形式,就不会报错了,个人感觉是文件的命名,dataset和utils与底层的源码命令一样引起的错误,请自辨,不一定对。
