Boto 3 textract Unkown Service

Question

Hello,  
  
I tried launching a Lambda function in us-east-2 utilizing the textract boto3 client and got this error;

```
module initialization error: Unknown service: 'textract'. Valid service names are:...
```

My function followed the documentation;

```
import boto3

client = boto3.client('textract')
```

Any help is greatly appreciated!

You can use following steps to add current version of AWS SDK to your Lambda function that supports Amazon Textract. This is also a common best practice when deploying Lambda functions in production is to package dependencies with your functions.  
  
**1. Create package for Lambda Layer**  
pip install boto3 --target python/.  
zip boto3-layer.zip -r python/  
  
**2. Create Lambda Layer**  
- In AWS Console go to Lambda  
- Click on Layers and Create Layer  
- Name: Boto3  
- Upload boto3-layer.zip file you just created.  
- Compatible runtimes: Python3.6 and Python 3.7  
- Click Create  
  
**3. Add Lambda Layer to Lambda function**  
In your Lambda function, click on “Layers”  
- Under Layers, click on “Add a layer”  
- Under Compatible layers: select the layer and version you just created and click Add.  
- Click Save to save changes to Lambda function.  
  
You should now be able to use Amazon Textract in your Lambda function.
