e8def1194d Replace GitHub API check with vLLM version check for PDL fix
The GitHub issue check had issues:
1. Network latency on import
2. Issue being closed does not mean the fix is in the installed vLLM version

Now skip the PDL workaround if vLLM version > 0.13.2, which is when
the upstream fix is expected to be included.

c8a585a589 Keep PDL module check but remove unnecessary env var setting
The check skips the GitHub API call for old vLLM versions.
No need to set TRITON_DISABLE_PDL for versions without PDL support.

bc0f1514f2 Remove unnecessary PDL module existence check
Old vLLM versions without PDL modules don't need the fix.
The patching code already handles missing modules gracefully.

9860d8859d Fix PDL patch: target utils.py source module and clear lru_cache
- Patch vllm.lora.ops.triton_ops.utils directly where supports_pdl is defined
- Clear lru_cache before patching to prevent stale cached results
- Add fused_moe_lora_op to consumer modules list
- Use *args, **kwargs in fake function for compatibility

e727c43685 Sync chat_template from tokenizer to vLLM
When using base models with custom chat templates applied after loading,
vLLM's internal tokenizer may not have the chat_template set. This causes
issues during RL training with vLLM inference.

This fix syncs the chat_template from the processing_class (the tokenizer
you loaded and configured) to vLLM's internal tokenizer during trainer
initialization, but only if vLLM's tokenizer does not already have one set.

594d3baffe Fix vLLM PDL bug on Blackwell GPUs (B200/B100)
vLLM's LoRA Triton kernels use tl.extra.cuda.gdc_wait() for PDL
optimization on SM90+ GPUs. This fails on SM100 (Blackwell) during
CUDA graph capture because Triton's pipeliner cannot handle gdc_wait
in complex kernels.

This fix:
- Detects SM100 GPUs and applies the workaround automatically
- Sets TRITON_DISABLE_PDL=1 environment variable
- Monkey-patches supports_pdl to return False in lora_expand_op and
  lora_shrink_op
- Checks GitHub issue #30872 status (with 3s timeout) to auto-disable
  the workaround once the upstream fix is merged
- Includes quick internet connectivity check (0.5s) to avoid delays
  when offline

Fixes the error:
'tt.elementwise_inline_asm' op pipeliner doesn't know how to predicate this op
LLVM ERROR: Fatal pipeliner error

762ef9a20f rl.py fixes: buffer reset, safer attribute access, typo fix
1. Auto-reset gradient checkpointing buffers after trainer.train()
   - Import and call reset_unsloth_gradient_checkpointing_buffers() in
     prepare_for_training_mode wrapper to free memory after training
     while keeping buffers ready for subsequent runs

2. Replace eval/exec with safer getattr/setattr
   - eval(f"trl.trainer.{trainer}") -> getattr(trl.trainer, trainer)
   - exec(f"...{unwrap} = ...") -> setattr(current_trainer, unwrap, ...)
   - exec(f"Trainer.prediction_step=...") -> direct assignment

3. Fix psutil.cpu_count() potentially returning None
   - Change psutil.cpu_count()+4 to (psutil.cpu_count() or 1)+4
   - Prevents TypeError on systems where cpu_count() returns None

4. Fix typo: oriignal_is_vlm_text -> original_is_vlm_text
