I’ve tried to simulate issues we had on production using a new instance of nexus.
The flow:

  1. After installation - create 3 pip repos
    a. pypi hosted
    b. pypi proxy - from pypi.org
    c. pypi group - which includes pypi hosted and proxied.
  2. Upload some packages into pypi hosted
  3. Start download list of packages (the last of them is torch which is not available on “hosted”)
    The index URL is pointed to this new instance.
  4. Same time look on
    Logs of the task - which show errors like timeout:
ERROR: Could not install requirement torch from http://r2d4-linux.dc.local:8081/repository/deepypigr/packages/torch/2.0.1/torch-2.0.1-cp38-cp38-manylinux1_x86_64.whl#sha256=5ef3ea3d25441d3957348f7e99c7824d33798258a2bf5f0f0277cbcadad2e20d (from -r scripts/requirements.txt (line 116)) because of HTTP error 404 Client Error: Not Found for url: http://r2d4-linux.dc.local:8081/repository/deepypigr/packages/torch/2.0.1/torch-2.0.1-cp38-cp38-manylinux1_x86_64.whl for URL http://r2d4-linux.dc.local:8081/repository/deepypigr/packages/torch/2.0.1/torch-2.0.1-cp38-cp38-manylinux1_x86_64.whl#sha256=5ef3ea3d25441d3957348f7e99c7824d33798258a2bf5f0f0277cbcadad2e20d (from http://r2d4-linux.dc.local:8081/repository/deepypigr/simple/torch/)

Why is that happening?
All the time it’s stuck on the torch, sometimes timeout, and sometimes all good. but if it’s stuck it’s on torch, is it because it’s heavy? what is the solution for this?

First you should check your client side for anti-viruses or proxies that may be interfering. One should also check the settings of reverse proxies if you’re using one.

if you are trying to install from pip client add --timeout 1000

Hi

we are hitting the same issue for pypi proxy.
