# TrOCR

TrOCR is Microsoft's transformer-based OCR model. It is trained for line-level text recognition, so crop your input to a single text region for best results.

{% hint style="info" %}
TrOCR is not available on the Serverless Hosted API. Run it on a [Dedicated Deployment](/deploy/dedicated-deployments.md) or [self-hosted Inference](https://inference.roboflow.com/).
{% endhint %}

## Code sample

Install dependencies:

```bash
pip install requests opencv-python
```

Set `URL` to your Dedicated Deployment URL or a local Inference server. Pass your [Roboflow API Key](https://app.roboflow.com/settings/api) via the `API_KEY` environment variable.

```python
import base64
import os
import urllib.request

import cv2
import requests

URL = "https://your-deployment.roboflow.cloud"
IMAGE_URL = "https://media.roboflow.com/inference/license_plate_1.jpg"
IMAGE_PATH = "license_plate.jpg"

urllib.request.urlretrieve(IMAGE_URL, IMAGE_PATH)
image = cv2.imread(IMAGE_PATH)
_, buffer = cv2.imencode(".jpg", image)
image_base64 = base64.b64encode(buffer).decode("utf-8")

response = requests.post(
    f"{URL}/ocr/trocr",
    json={
        "api_key": os.getenv("API_KEY"),
        "image": {"type": "base64", "value": image_base64},
    },
)
print(response.json()["result"])
```

The code above prints the recognized text to the terminal:

```
TOTAL
```

{% hint style="info" %}
Set `URL` to match your deployment target:

* `http://localhost:9001` for a local [Inference](https://inference.roboflow.com/) server.
* Your [Dedicated Deployment](/deploy/dedicated-deployments.md) URL for a private endpoint.
  {% endhint %}
