Insufficient Container Space for Copying Data

Symptom

When a ModelArts training job is running, the following error is reported in the log. As a result, data cannot be copied to the container.

OSError:[Errno 28] No space left on device

Possible Causes

The container space is insufficient for downloading data.

Solution

1. Check whether data is downloaded to the /cache directory. Each GPU node has a /cache directory with 4 TB of storage.
2. Check whether GPU resources are used. If CPU resources are used, /cache and the code directory share 10 GB of memory. As a result, the memory is insufficient. In this case, use GPU resources instead.
3. Add the following environment variable to the code:

   import os
   os.system('export TMPDIR=/cache')
