**TL;DR:** pinecone.init() was removed after SDK v2. On the current SDK, construct Pinecone() and use pc.Index(name). Fix Note the environment parameter is gone too: serverless indexes do not take an environment string, and the client resolves routing from the key. Migrate the three lines instead.

## The error

```text
AttributeError: module 'pinecone' has no attribute 'init'
```

## The fix

# AttributeError: module 'pinecone' has no attribute 'init'

## The error

```
AttributeError: module 'pinecone' has no attribute 'init'
```

## Cause

Code written for SDK v2 calling `pinecone.init(api_key value ..., environment=...)`. The v3 SDK replaced module-level `init` with the `Pinecone` client class. This is the single most common error when following pre-2024 tutorials.

## Fix

```
# before (v2, broken now)
import pinecone
pinecone.init(api_key value "...", environment="us-west1-gcp")
index = pinecone.Index("quickstart")

# after (v3+)
from pinecone import Pinecone
pc = Pinecone()
index = pc.Index("quickstart")
```

Note the environment parameter is gone too: serverless indexes do not take an environment string, and the client resolves routing from the key.

## Trap

Downgrading to `pinecone-client` 2.x to make `init` work again. That revives every bug fixed since and breaks serverless. Migrate the three lines instead.

## When to use this

- You are seeing this exact error message; match the block above, not just part of it.
- The failing call matches the scenario in the title: Python AttributeError.
- You want the fastest verified fix before digging through logs.

## When not to use this

- Your error text differs from the block above; close cousins often have different causes.
- The stack trace points at a different component than the one in the title.
- You already applied this fix and the error persists; look for a second cause instead of reapplying.

## Compatibility

- Not pinned to a specific version; follows current Python behavior.

## Also seen as

- `client class. This is the single most common error when following pre-2024 tutorials.
