Helios model training strategies: `is_amplify_history` and `restrict_self_attn`.
Technical Positioning
A real-time long video generation model.
SaaS Insight & Market Implications
This issue queries the application of specific training strategies (`is_amplify_history`, `restrict_self_attn`) in Helios's base model weights, given their default `false` configuration. The developer is seeking clarity on the model's underlying training methodology. This indicates a need for transparent documentation regarding model architecture and training parameters, which is crucial for reproducibility, fine-tuning, and understanding model behavior. For B2B SaaS in the AI model space, clear communication of such technical details builds developer confidence and facilitates integration. Ambiguity around core training strategies can hinder adoption by enterprises that require deep insight into model provenance and performance characteristics for compliance, security, and optimization.

is_amplify_history 和 restrict_self_attn 问题
is_amplify_history: false
restrict_self_attn: false
大佬，现在的配置文件中这两个参数默认配置都是false，想请教下现在的base权重使用这两个训练策略了吗？

主要都是模拟推理过程吧。不加噪意味着完全干净的内容，但是模型推理出来的结果或多或少会和真实世界完全干净的内容有所差异

pipe填wan或者helios的路径都行。transformer得看你训练的时候用了哪个transformer，比如stage-1-init用的是wan的transformer，此时填wan的路径，其他阶段以此类推。

排除代码/权重加载问题前提下，训练一开始是这样的，往后训会逐渐连贯。你这个大概训了多久？batchsize和lr分别是多少？
您好，我训练了8000step, batchsize1，lr固定5e-5
bs有点小，可以试着把`random_drop_t2v_ratio`关小，不然模型没学多少v2v任务
