tensorboardX突然无法正常工作

Question

当我键入命令时，tensorboardX无法正常工作，并出现提示：tensorboard --logdir = 201903281848 --port = 30001

Traceback (most recent call last):
  File "/home/user/anaconda/envs/jointpy35/bin/tensorboard", line 7, in <module>
    from tensorboard.main import run_main

昨天我可以正常使用它，我不知道哪个文件已升级。
