（一）发现执行问题
PS D:\PycharmProjects\PyCharm> tensorboard
tensorboard : 无法将“tensorboard”项识别为 cmdlet、函数、脚本文件或可运行程序的名称。请检查名称的拼写，如果包括路径，
请确保路径正确，然后再试一次。

请确保路径正确，然后再试一次。
（二）原因及修改
这是tensorboard执行程序没有在环境变量中。首先需要找到tensorboard.exe，然后将其路径放到系统变量path中。我的tensorboard已经下载，安装好。在C:\Users\jsg\Anaconda3\Scripts中找到tensorboard.exe。然后加到环境变量
（三）打开shell命令窗口
然后，在logs所在的路径下，按住shift，右键执行“在此处执行打开powershell命令”，
PS D:\PycharmProjects\PyCharm> tensorboard --logdir=logs
