Have you ever tried to reassign values in a TensorFlow tensor like you would in NumPy, only to hit the frustrating "EagerTensor object does not support item assignment" error? 😤 Let’s break down why this happens and how TensorFlow handles mutable data.

🔸 𝐈𝐦𝐦𝐮𝐭𝐚𝐛𝐥𝐞 𝐓𝐞𝐧𝐬𝐨𝐫𝐬: TensorFlow's tf.Tensor is immutable, meaning its values can't be changed after creation. This design ensures efficient execution on GPUs and TPUs.

🔸 𝐆𝐫𝐚𝐩𝐡-𝐁𝐚𝐬𝐞𝐝 𝐂𝐨𝐦𝐩𝐮𝐭𝐚𝐭𝐢𝐨𝐧: TensorFlow builds a graph of operations. Each tensor is a node in this graph. Allowing direct assignments would disrupt the graph's structure, making it hard to track dependencies and optimize computations.

tf.Variable is TensorFlow’s way to handle mutable data. Here’s how it works:

𝐂𝐫𝐞𝐚𝐭𝐞 𝐚 𝐕𝐚𝐫𝐢𝐚𝐛𝐥𝐞: Instead of a tf.Tensor, create a tf.Variable. This variable holds a tensor that can be modified.

𝐀𝐬𝐬𝐢𝐠𝐧 𝐕𝐚𝐥𝐮𝐞𝐬: Use the assign method to change the variable’s value.
