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¶
Check whether data is downloaded to the /cache directory. Each GPU node has a /cache directory with 4 TB of storage.
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.
Add the following environment variable to the code:
import os os.system('export TMPDIR=/cache')
