解决

依次修改以下文件：
/mistgpu/site-packages/tensorboardX/summary.py中
def image(tag, tensor, rescale=1, dataformats=‘HWC’)的入口参数’CHW’修改为‘HWC’;
/mistgpu/site-packages/tensorboardX/writer.py中的
def add_image(
self,
tag: str,
img_tensor: numpy_compatible,
global_step: Optional[int] = None,
walltime: Optional[float] = None,
dataformats: Optional[str] = ‘HWC’)
中的’CHW’修改为‘HWC’;
即可运行正常，具体原因见https://blog.csdn.net/weixin_40740309/article/details/114701132

在修改过程中可能会遇到只能修改只读文件，在Linux系统中，可以利用chmod 777 filename指令，修改文件权限。
