CLI fails on startup: AttributeError: module 'torch' has no attribute 'uint64' via transformers/safetensors

[baliqbalpe]

Description

• Running fuzzyai -h crashes immediately during import. The crash originates from safetensors importing torch.uint64, which PyTorch does not provide. This looks like a dependency-compatibility problem introduced by newer safetensors (and transitively via transformers), not user code.
• Suggest pinning safetensors < 0.5.0 or gating/lazy-importing local LLM providers so heavy deps aren’t imported unless used.

Environment

• Install source: pip install git+https://github.com/cyberark/FuzzyAI.git (resolved to commit 2d1d4e6bfc5fbc3b5349f6387d1353f125809402)
• Python: 3.10
• Platform: Linux x86_64 wheels shown in pip logs
• Key packages (from install log):
  • fuzzyai==1.0.0
  • torch==2.2.2
  • transformers==4.51.3
  • safetensors==0.6.1
  • sentence-transformers==2.7.0

Steps to reproduce

pip install --upgrade pip
pip install git+https://github.com/cyberark/FuzzyAI.git
fuzzyai -h

Expected behavior

• CLI prints help text.

Actual behavior

• Immediate crash with AttributeError: module 'torch' has no attribute 'uint64'.

RuntimeError: Failed to import transformers.generation.utils because of the following error:

Workarounds tested

• Downgrading safetensors resolves the crash:

pip uninstall -y safetensors
pip install "safetensors==0.4.3"
# then
fuzzyai -h  # works

Proposed fixes

• Pin dependency in pyproject.toml/requirements:
  • safetensors>=0.4.3,<0.5.0
