追溯 pytorch 中已弃用的警告

Question

我正在使用这里的代码在我的数据上训练 yolov3： https://github.com/cfotache/pytorch_custom_yolo_training/

但是我收到了这个烦人的弃用警告

Warning: indexing with dtype torch.uint8 is now deprecated, please use a dtype torch.bool instead. (expandTensors at /pytorch/aten/src/ATen/native/IndexingUtils.h:20)

我尝试使用 python3 -W ignore train.py 我尝试添加：

import warnings
warnings.filterwarnings('ignore')

但警告仍然存在。

我在 Whosebug 上找到了这段代码，它在警告时打印堆栈，

import traceback
import warnings
import sys

def warn_with_traceback(message, category, filename, lineno, file=None, line=None):

    log = file if hasattr(file,'write') else sys.stderr
    traceback.print_stack(file=log)
    log.write(warnings.formatwarning(message, category, filename, lineno, line))

warnings.showwarning = warn_with_traceback

这是我得到的：

  File "/content/pytorch_custom_yolo_training/train.py", line 102, in <module>
   loss = model(imgs, targets)
  File "/usr/local/lib/python3.6/dist-packages/torch/nn/modules/module.py", line 532, in __call__
    result = self.forward(*input, **kwargs)
  File "/content/pytorch_custom_yolo_training/models.py", line 267, in forward
    x, *losses = module[0](x, targets)
  File "/usr/local/lib/python3.6/dist-packages/torch/nn/modules/module.py", line 532, in __call__
    result = self.forward(*input, **kwargs)
  File "/content/pytorch_custom_yolo_training/models.py", line 203, in forward
    loss_x = self.mse_loss(x[mask], tx[mask])
  File "/usr/lib/python3.6/warnings.py", line 99, in _showwarnmsg
    msg.file, msg.line)
  File "/content/pytorch_custom_yolo_training/train.py", line 29, in warn_with_traceback
    traceback.print_stack(file=log)
  /pytorch/aten/src/ATen/native/IndexingUtils.h:20: UserWarning: indexing with dtype torch.uint8 is now deprecated, please use a dtype torch.bool instead.

转到堆栈中提到的文件和函数，我没有找到任何 uint8。我该如何解决问题甚至停止收到这些警告？

Answer 1

找到问题了。行：loss_x = self.mse_loss(x[mask], tx[mask]) mask 变量是一个 ByteTensor，已弃用。只是将其替换为 BoolTensor

Answer 2

这适用于我的情况：添加

obj_mask = obj_mask.type(torch.BoolTensor)
noobj_mask = noobj_mask.type(torch.BoolTensor)

之前

loss_x = self.mse_loss(x[obj_mask], tx[obj_mask])

在in models.py.

Answer 3

这个很好用

obj_mask = obj_mask.bool()
noobj_mask = noobj_mask.bool()
