The first time you use tensorflow’s debug tool, but when you use it for the second time, there is always a shortage of space, which can be solved through the following steps.

  df -h

Find that the root directory is full, then go to the root directory and check the occupied directory  

  du –max-depth=1 -h

  It is found that TMP directory takes up a lot of space

Sure enough, when you go to TMP, you find files related to tfdbg. Just delete them  。
