关于#CUDA OUT OF MEMORY#的问题，如何解决？

在使用Stable Difussion的时候， free memory 和 already allocated memory 相加小于所需内存 但是显示CUDA out of
memory，在网上看了下，在python.exe里输入以下代码 os.environ["PYTORCH_CUDA_ALLOC_CONF"] = "max_split_size_mb:32" 现在是free memory很小，但是reserved memory 很大，请大神指点一下

• @Override
  Traceback (most recent call last):

      model.validation(val_loader, current_iter, tb_logger, opt['val']['save_img'])

      self.output = net_g.test(lq_input)
    File "/home/iecy/anaconda3/envs/pytorch/lib/python3.6/site-packages/torch/autograd/grad_mode.py", line 28, in decorate_context
      return func(*args, **kwargs)
    File "/home/iecy/pycharm/Openbayes/QuanTexSR-main/basicsr/archs/quantsr_arch.py", line 417, in test
      input = self.content_model(input)
    File "/home/iecy/anaconda3/envs/pytorch/lib/python3.6/site-packages/torch/nn/modules/module.py", line 1051, in _call_impl
      return forward_call(*input, **kwargs)
    File "/home/iecy/pycharm/Openbayes/QuanTexSR-main/basicsr/archs/rrdbnet_arch.py", line 117, in forward
      feat = self.lrelu(self.conv_up2(F.interpolate(feat, scale_factor=2, mode='nearest')))
    File "/home/iecy/anaconda3/envs/pytorch/lib/python3.6/site-packages/torch/nn/functional.py", line 3690, in interpolate
      return torch._C._nn.upsample_nearest2d(input, output_size, scale_factors)
  	}
  

  其中上面有一行就是问题所在。我将它修改之后，就没有再出现cuda out of memory.
