训练问题请教

@你好，
执行python @@main.py时提示：
Traceback (most recent call last):
File "main.py", line 40, in
trainer.load_weights(trainer.find_last())
File "/home/passwd123123/zyx/DFANet/train.py", line 189, in find_last
"Could not find weight files in {}".format(dir_name))
FileNotFoundError: [Errno 2] Could not find weight files in ./log/dfanet20191211T1533

然后去看提示中的train.py文件最后发现是下面的checkpoint为空导致的：
# Find the last checkpoint
checkpoints = next(os.walk(dir_name))[2]
checkpoints = filter(lambda f: f.startswith("model"), checkpoints)
checkpoints = sorted(checkpoints)
if not checkpoints:
不知道这个checkpoints有什么用，是先要手动往./log/dfanet20191211T1533目录存放model文件吗？
