我正在使用Pycharm与python 3.9，torch 1.8.1+cu111和tensorboard 2.6.0.当我尝试导入SummaryWriter时：

from torch.utils.tensorboard import SummaryWriter

出现以下错误：

* Traceback (most recent call last):

  File "/data/heisery/Yaronhome/PycharmProjects/CSSC_pytorch/tensorboard.py", line 18, in <module>
    from torch.utils.tensorboard import SummaryWriter
  File "/usr/local/lib/python3.8/dist-packages/torch/utils/tensorboard/__init__.py", line 1, in <module>
    import tensorboard
  File "/data/heisery/Yaronhome/PycharmProjects/CSSC_pytorch/tensorboard.py", line 18, in <module>
    from torch.utils.tensorboard import SummaryWriter*

**ImportError: cannot import name 'SummaryWriter' from partially initialized module 'torch.utils.tensorboard' (most likely due to a circular import) (/usr/local/lib/python3.8/dist-packages/torch/utils/tensorboard/__init__.py)**

这是我的导入列表：

import torch
import torch.nn as nn
from torch.utils.data import DataLoader
import torchvision
import torchvision.transforms as transforms
import matplotlib.pyplot as plt
import sys
from torch.utils.tensorboard import SummaryWriter
writer = SummaryWriter('runs/mnist')

device = torch.device('cuda:0' if torch.cuda.is_available() else 'cpu')
