× Dependency resolution exceeded maximum depth ╰─> Pip cannot resolve the current dependencies as the dependency graph is too complex for pip to solve efficiently.

hint: Try adding lower bounds to constrain your dependencies, for example: 'package>=2.0.0' instead of just 'package'.

  error: Microsoft Visual C++ 14.0 or greater is required. Get it with "Microsoft C++ Build Tools": https://visualstudio.microsoft.com/visual-cpp-build-tools/

  hint: This usually indicates a problem with the package or the build environment.

help: chroma-hnswlib (v0.7.3) was included because chromadb (v0.4.14) depends on chroma-hnswlib 解决： python版本降级到Python 3.11
