- **Domain:** python
- **Category:** network_error
- **Verification:** ai_generated
- **Fix Rate:** 80%

## Root Cause

Slow or unstable network, or a proxy throttling large wheel downloads.

## Version Compatibility

| Version | Status | Introduced | Deprecated |
|---------|--------|------------|------------|

## Workarounds

1. **** (90% success)
   ```
   pip install --timeout 120 --retries 5 foo
   ```
2. **** (85% success)
   ```
   mkdir -p ~/.pip
cat > ~/.pip/pip.conf <<'EOF'
[global]
timeout = 120
retries = 5
EOF
pip install foo
   ```

## Dead Ends

- **** — Bypasses cache but does not address slow network; may worsen by re-downloading dependencies. (60% fail)
- **** — Same timeout will recur; retries waste bandwidth. (70% fail)
