You can use this code to generate a 64x64 base64 encoded image with the text "deep learning":

```python
import cv2 
import numpy as np 
from base64 import b64encode

# Create a blank 64x64 black image 
img = np.zeros((64,64,3), np.uint8) 
img.fill(0) 

# Write some text on the image 
text = "deep learning" 
font = cv2.FONT_HERSHEY_DUPLEX 

# Set up text location 
text_size, text_bottom = cv2.getTextSize(text, font, 0.75, 1) 
x, y = 24, 64 

# Write text on the image 
cv2.putText(img, text, (x, y), font, 0.75, (255, 255, 255), 1) 

# Convert image to base64 
encoded = b64encode(cv2.imencode('.jpg',img)[1]).decode('utf-8') 

print(encoded)
```

This will print the base64 encoded string which you can use to embed the image in HTML, PDF etc.
