Root Cause

A network middlebox, proxy, or rate limiter is resetting the TCP connection during large index downloads.

中文

网络中间件、代理或限流器在大型索引下载期间重置了 TCP 连接。

Workarounds

  1. 85% success 
    pip install --retries 10 --timeout 60 --index-url https://pypi.tuna.tsinghua.edu.cn/simple numpy
  2. 90% success 
    curl -L -O https://files.pythonhosted.org/packages/.../numpy-2.1.0-cp311-cp311-manylinux_2_17_x86_64.whl
pip install ./numpy-2.1.0-cp311-cp311-manylinux_2_17_x86_64.whl

Dead Ends

Common approaches that don't work:

  1. 80% fail

    Disabling the cache does not prevent the connection reset.

  2. 95% fail

    Reducing retries makes the failure immediate rather than fixing the network issue.

  3. 90% fail

    Lowering the timeout causes more timeouts and does not address the reset.
