Keval MorabiaandRinZ27 5dc17dfd15 [Security] Enable torch.load(weights_only=True) for secure checkpoint loading + trust_remote_code fix (#1181) 
### What does this PR do?

- Add secure checkpoint loading support using
`torch.serialization.add_safe_globals([cls])`. This also removes 1
existing pickle usage.
- Remove hard-coded `trust_remote_code=True`
- Replaces https://github.com/NVIDIA/Model-Optimizer/pull/1056 by
@RinZ27

### Testing
<!-- Mention how have you tested your change if applicable. -->

CICD tests ran

## Summary by CodeRabbit

* **New Features**
* Added safe checkpoint save/load helpers and a --trust_remote_code CLI
flag in examples to control remote-code loading.

* **Bug Fixes**
* Checkpoint loading now defaults to safer, weights-only semantics to
reduce arbitrary-code exposure.

* **Documentation**
* CHANGELOG updated with security guidance and opt-in procedure for
unsafe checkpoint loading.

* **Tests**
  * New unit tests validating the safe-load behavior.

h-guo18 7f5fd65003 [Feat]FakeBaseModel for offline eagle; Kimi-K2.5 fixes; (#1052) 
### What does this PR do?

Adds `FakeBaseModel` for offline EAGLE training and several Kimi-K2.5
compatibility fixes.

- **New**: `FakeBaseModel` — lightweight model that loads only `lm_head`
and `embed_tokens` from a local checkpoint, avoiding full model weight
loading during offline training. Configured via `FakeBaseArguments` and
integrated into `load_vlm_or_llm`.
- **Fix**: `_find_base_model_parts` — support Kimi-K2.5 VLM layout
(`language_model.model` path)
- **Fix**: offline mode lm_head access and CompressedTensors ignore path
- **Fix**: Kimi-K2.5 decoder `past_key_value`/`past_key_values` argument
mismatch
- **Fix**: `rglob` for `.pt` discovery in nested offline data dirs;
single-node GPU count respects `CUDA_VISIBLE_DEVICES`

Type of change: Bug fix, new feature

### Testing
Tested offline EAGLE training for Kimi-K2.5 end-to-end.

## Summary by CodeRabbit

* **New Features**
* Lightweight fake-base model support for offline speculative-decoding
training

* **Improvements**
* Added CLI flags: --use_fake_base_for_offline, --trust_remote_code, and
--fsdp
  * Expanded offline .pt discovery to include nested subdirectories
* Better GPU detection with explicit single-node logging; FSDP enabled
only when requested
* Model loading and launch tooling now honor offline and
trust-remote-code flags

* **Bug Fixes**
* Improved compatibility with legacy transformer / Kimi-K2 call
signatures

* **Tests**
* Added tests covering fake-base loading and offline training workflows

h-guo18 b8a4586702 Refactor: Eagle data loading (#668) 
## What does this PR do?

**Type of change:** Refactor <!-- Use one of the following: Bug fix, new
feature, new example, new tests, documentation. -->

**Overview:** 
Jira ticket: https://jirasw.nvidia.com/browse/OMNIML-2955

Main changes :

- Consolidate Eagle data loading with @ChenhanYu 's implementation of
`transformers_dataset.py`

- Refactor: baked the following logics from `example/main.py` to
`modelopt/torch` for cleaner example entrance:
  - default config selecting and merging with custom config
  - tokenizer post-processor (chat template and pad_tok_id)
  - d2t loading 
- Implementation refactor: In HF workflow, reuse base modfel's input
hidden states as input_embedding, instead of calculating from input_ids.
This has two main benefits:
    - Easier VLM support, which has various embedding processing logics.
    - Training effieicy.
    
- Deprecating eagle1 from the example. It is still available by setting
custom config.
  
 - Other minor fixes and readme updates.

## Usage
<!-- You can potentially add a usage example below. -->

```python
# Add a code snippet demonstrating how to use this
```

## Testing
<!-- Mention how have you tested your change if applicable. -->

Tested that training curves after changes (both online&offline) is
identical with original branch:
