@Lob in JPA, Hibernate

http://www.java2s.com/Tutorials/Java/JPA/0250__JPA_Lob_Column.htm



The following code shows how to save byte array to database with @Lob annotation.

LOBs have two types in the database: character large objects, called CLOBs, and binary large objects, or BLOBs.

A CLOB column holds a large character sequence, and a BLOB column can store a large byte sequence.

The Java types mapped to BLOB columns are byte[] Byte[] , and Serializable types, while char[] Character[] , and String objects are mapped to CLOB columns.

 @Lob 
  private byte[] picture;   //BLOB
or

 @Lob 
  private Byte[] picture;   //BLOB


 @Lob 
  private char[] picture;   // CLOB
or

 @Lob 
  private Character[] picture;  //CLOB

Fixing the DeepSpeed Import Error While Fine-Tuning the Qwen Model

While fine-tuning the Qwen model, I encountered an error in the finetune.py script: ImportError : cannot import name 'deepspeed' from 'transformers.deepspeed' After some investigation, I discovered the issue stems from a recent update in the Transformers library. The transformers.deepspeed module has been deprecated and replaced by transformers.integrations . To fix this, you need to update the import statement in your script. The Fix Replace this: from transformers.deepspeed import deepspeed With this: from transformers.integrations import deepspeed This small change resolved the error, allowing the fine-tuning process to proceed smoothly. Additional Resources For more details, refer to the discussion in the official Transformers GitHub repository: Issue #34582 Remember to keep your library versions up-to-date to avoid similar issues in the future!
