How to search local image (without url) using Google lens by python.

[xin-ran-w]

I have a image store in my local device, and I want to search it on web, here is my code, but it didn't work.

    def encode_pil_to_base64(image):
        buffered = BytesIO()
        image.save(buffered, format="JPEG")
        img_str = base64.b64encode(buffered.getvalue()).decode()
        return img_str
    
    image_url = f"data:image/jpeg;base64,{encode_pil_to_base64(image)}"

    params = {
        "engine": "google_lens",
        "url": image_url,
        "api_key": os.getenv("SERP_API_KEY"),
        "hl": "en",
        "country": "US"
    }
    search = GoogleSearch(params)
    results = search.get_dict()

The error is shown here:

Traceback (most recent call last):

    results = search.get_dict()
