Overview

Concrete tool for installing all required OpenTelemetry dependencies for AI observability provided by the arize-phoenix-otel Python package.

Description

The arize-phoenix-otel package (version 0.14.0 as of this writing) is a meta-package that bundles the complete set of OpenTelemetry SDK components, OTLP exporters, and OpenInference semantic conventions needed to instrument LLM applications and export traces to Phoenix or any OTLP-compatible collector.

A single pip install command resolves and installs the following transitive dependencies:

opentelemetry-sdk: Core tracing SDK providing TracerProvider, Resource, and span processor abstractions.
opentelemetry-exporter-otlp: Meta-package that pulls in both HTTP and gRPC OTLP exporters (opentelemetry-exporter-otlp-proto-http and opentelemetry-exporter-otlp-proto-grpc).
opentelemetry-proto (>=1.12.0): Protobuf message definitions for the OTLP wire format.
opentelemetry-semantic-conventions: Standard OTel semantic attribute keys.
openinference-semantic-conventions (>=0.1.17): AI-specific semantic attribute keys for LLM spans (e.g., llm.token_count.prompt, input.value, output.value).
openinference-instrumentation (>=0.1.38): Base instrumentation framework with entry point discovery for auto-instrumentation of LLM libraries.
typing-extensions (>=4.5, <5): Backported typing features for Python 3.8+ compatibility.
wrapt: Function wrapping utilities used by instrumentation hooks.

The package also provides Phoenix-aware wrapper classes (TracerProvider, SimpleSpanProcessor, BatchSpanProcessor, HTTPSpanExporter, GRPCSpanExporter) that auto-infer configuration from environment variables.

Usage

Use this installation command when:

Bootstrapping a new Python project that needs LLM tracing.
Adding observability to an existing LLM application.
Ensuring all OTel dependencies are at compatible versions.
Needing Phoenix-specific convenience wrappers on top of the standard OTel SDK.
