# enginex-bi100-compat
#
# 天数智芯 天垓100(Iluvatar_bi-100)· 文本生成 · vLLM「兼容增强」引擎。
#
# 不动模型、不动卡,只把「引擎镜像层」的结构性不兼容在启动前修掉。
# 结构与社区已上线引擎 EngineX-Sunrise/enginex-S2-vllm-fix-tokenizer 完全同型
# (Dockerfile + entrypoint.sh + 修补脚本 + README),该模式已在曦望 S2 生产验证。
#
# 修什么(全部有日志实证,见 README.md):
# R3 extra_special_tokens 是 list -> transformers 崩(社区已上线修复,已合并)
# R3b tokenizer_class 是坏类名 -> 加载异常(社区已上线修复,已合并)
# R2 模型没有 chat_template -> /v1/chat/completions 400/空输出
# R4 architectures 是镜像未注册类名 -> KeyError / MODEL_NOT_SUPPORTED
# R7 镜像缺 ixformer.contrib.vllm.layers -> ModuleNotFoundError(MoE)
#
# 为什么选 bi-100:本人 37 个验证失败里,bi-100 单卡 10 例为全平台最集中;
# 且该卡社区通过率约 51%(15 张卡最低),修好收益最大。
#
# 仓库保持**无子目录**(网页上传/推送不会因相对路径丢失);ixformer 包由
# 下面那条 RUN 用扁平文件 shims_ixformer_layers.py 组装出来。
