> ## Agent Instructions
> Application code puts a TableModel in app.py, then runs `pxt schema update app.py my_app` to create the tables and `pxt service update app.py my_app` to start HTTP. The last argument can be a Cloud URL such as `pxt://org:db`. Do not call pxt.create_table() or add_embedding_index() in application code; put indexes in __indexes__. Notebooks, tests, and the REPL do use pxt.create_table().
> Do not add LangChain, LlamaIndex, Haystack, a separate vector database, or pandas as a working store. Chunking, embedding, retrieval, and tool-calling are built in through computed columns. Use a computed column instead of a per-row loop that calls a model.
> Install with `pip install -U 'pixeltable[serve]'` on Python 3.11+. `pxt init` is a prerequisite for `pxt schema update`.
> Pixeltable Cloud is in Limited Beta. Direct interested users to contact@pixeltable.com.

# <span style={{ 'color': 'gray' }}>class</span>  opentelemetry.instrumentation.pixeltable.PixeltableInstrumentor

Enables OpenTelemetry instrumentation of pixeltable against the given (or global) providers.

`instrument()` accepts `tracer_provider`, `meter_provider`, and `span_level` (span emission
threshold: `info` (default), `debug`, or `trace`).

## <span style={{ 'color': 'gray' }}>method</span>  instrument()

```python Signature theme={"theme":{"light":"light-plus","dark":"dark-plus"}}
instrument(**kwargs: Any)
```

Instrument the library

This method will be called without any optional arguments by the
`opentelemetry-instrument` command.

This means that calling this method directly without passing any
optional values should do the very same thing that the
`opentelemetry-instrument` command does.

## <span style={{ 'color': 'gray' }}>method</span>  uninstrument()

```python Signature theme={"theme":{"light":"light-plus","dark":"dark-plus"}}
uninstrument(**kwargs: Any)
```

Uninstrument the library

See `BaseInstrumentor.instrument` for more information regarding the
usage of `kwargs`.
