Add a reminder for the illegal memory error

[Yi-FanLi]

When using the GPU version of the neighbor stat code, one may encounter the following issue and the training will stop:

[2024-05-24 23:00:42,027] DEEPMD INFO    Adjust batch size from 1024 to 2048
[2024-05-24 23:00:42,139] DEEPMD INFO    Adjust batch size from 2048 to 4096

2024-05-24 23:00:52.071120: E tensorflow/compiler/xla/stream_executor/cuda/cuda_event.cc:29] Error polling for event status: failed to query event: CUDA_ERROR_ILLEGAL_ADDRESS: an illegal memory access was encountered

This should be due to some issue of TensorFlow. One may use the environment variable DP_INFER_BATCH_SIZE to avoid this issue.

This PR remind the user to set a small DP_INFER_BATCH_SIZE to avoid this issue.

Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai generate interesting stats about this repository and render them as a table.
  • @coderabbitai show all the console.log statements in this repository.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

CodeRabbit Commands (invoked as PR comments)

But what is "illeagle"?

My bad lol. I have renamed this branch and opened a new PR.
