error：

solution：

You are trying to compare predicted and labels. However, your predicted is an np.array while labels is a torch.tensor therefore eq() (the == operator) cannot compare between them.
Replace the np.argmax with torch.argmax:

实际上的solution：
将 pids = pids.cuda() 去掉，因为这里cuda会将numpy转化为tensor，而实际上是用numpy 而不是tensor

文件名字修改：
srcpath = ‘/mnt/hgfs/share/DT2/testdata’
a = 81002

for root,dirs,files in os.walk(srcpath):
a += 1
b = 0
for imagefile in files[0::2]:
b += 1
jsonfile = files[files.index(imagefile)+1]
oldimage = root + ‘/’ + imagefile
newimage = root + ‘/’ + ‘20190704000’ + str(a) + ‘000’ + str(b) + ‘.jpg’
oldjson = root + ‘/’ + jsonfile
newjson = root + ‘/’ + ‘20190704000’ + str(a) + ‘000’ + str(b) + ‘.json’
os.rename(oldimage,newimage)
os.rename(oldjson,newjson)
