[BUG] Illegal instruction (core dumped) on x86_64 CPU without AVX2 (error 132)

[niutech]

🐛 Bug Description

I want to run localGPT on my Intel Core i5-2400 CPU, but it doesn't support AVX2 instruction. However, localGTP relies on lancedb, which requires AVX2. This is a known issue: lance-format/lance#2195, lancedb/lancedb#592, lancedb/lancedb#1018, lancedb/lancedb#1437.

🔄 Steps to Reproduce

Try to run system_health_check.py.

✅ Expected Behavior

Make me run localGPT.

❌ Actual Behavior

Illegal instruction (core dumped), returned error 132.

🖥️ Environment Information

Desktop:

• OS: Ubuntu 24.04
• Python Version: 3.12

🤔 Possible Solution

Replace lancedb with another vector database?

I was able to work it around by compiling lancedb from source using instructions from lance-format/lance#2195 (comment)
