Here's the reproduction:

import os
import tempfile
from pathlib import Path
from ray._private.runtime_env.packaging import _zip_directory
from zipfile import ZipFile

with tempfile.TemporaryDirectory() as tmp_dir:
    # Prepare test directory
    path = Path(tmp_dir)
    subdir = path / "subdir"
    subdir.mkdir(parents=True)
    file1 = subdir / "file1.txt"
    with file

... to make it easier to read Vespa documentation on an e-reader / offline

Vespa documentation is generated using Jekyll from .md and .html files, look into options for generating the artifact as part of site generation (there might be plugins we can use here)

The documentation for creating complex inference graphs should include what components can be connected to what, and how the overall graph should behave.

For example, all inference graphs need to end with a single node, whether its a combiner combining multiple inputs, or a transformer, or a model--the graph can't split and then never rejoin, etc.

ReloadableInferEngine::proc_initialize中使用TaskExecutor的是个单例，那么多个模型会一次去设置、启动同一个TaskExecutor；
在调用schedule()之后，TaskExecutor如何确定去调用哪个模型呢？

The format of current master branch UDF output, eva-reuse and my SSD object detector is different. Need a sync format.
