问题描述
我在如下环境中成功从 main 分支编译并安装 ktransformers==0.3.2+cu122torch26fancy，不过它目前不包含 sft 子模块
我尝试在 KT-SFT 下从源编译遇到如下问题：
CMake Error: The source directory "/data/zyx/LLaMA-Factory/ktransformers/KT-SFT/csrc/ktransformers_ext" does not appear to contain CMakeLists.txt.
完整 stderr 如下：

复现步骤
我使用以下命令成功构建了 ktransformers
uv venv && source .venv/bin/activate
uv pip install torch==2.6.0 torchvision==0.21.0 torchaudio==2.6.0 --index-url https://download.pytorch.org/whl/cu124
uv pip install -r requirements-local_chat.txt
uv pip install -r ktransformers/server/requirements.txt
MAX_JOBS=$(nproc) KTRANSFORMERS_FORCE_BUILD=TRUE uv pip install -v . --no-build-isolation
uv pip install third_party/custom_flashinfer/
在切换到 KT-SFT 子目录下，注释了 pyproject.toml 的 license-files 部分以保证 setuptools 能正确识别
readme = "README.md"
license = "Apache-2.0"
# license-files = ["LICENSE"]
uv pip install -r requirements-sft.txt
MAX_JOBS=$(nproc) KTRANSFORMERS_FORCE_BUILD=TRUE uv pip install -v . --no-build-isolation
