Understanding the Problem

A common scenario involves having a tensor representation of an image, and you want to transform it into a base64 string. This can be useful for embedding images in HTML, sending images over the network, or storing them in a text format.

For example, you might have a tensor like this:

You might encounter difficulties when trying to convert this tensor directly to a base64 image using common libraries.

Solution Overview

To successfully convert a tensor to a base64 image string, you need to follow these steps:

Convert the Tensor to a PIL Image: This step uses the torchvision library to transform the tensor.

Convert the PIL Image to Bytes: This creates a byte representation of your image.

Encode the Bytes to Base64: The final step is to convert the byte sequence into a base64 string.

Step 1: Convert Tensor to PIL Image

Here's how to convert your tensor into a PIL image using torchvision:

Step 2: Convert PIL Image to Bytes

Next, you will need to convert this PIL image into bytes:
