ImportError: TensorBoard logging requires TensorBoard version 1.15 or above.

To resolve the `ImportError` related to TensorBoard, you need to ensure that you have installed the required version of TensorBoard.

You can update TensorBoard by using the following command in your terminal or command prompt:

pip install --upgrade tensorboard

If you already have TensorBoard installed and still encounter the error, you might have multiple versions of TensorFlow installed, and your code may be using an older version. In such cases, you can try specifying the version explicitly by importing `tensorboard` from the specific TensorFlow version you want to use:

from tensorflow import __version__ as tf_version
import tensorboard as tb
tb_version = tb.__version__

if tb_version != tf_version:
    raise ImportError(f"TensorBoard logging requires TensorBoard version {tf_version} or above, but found version {tb_version}")

This code will ensure that the installed TensorBoard version matches the TensorFlow version you have.

Remember that these solutions assume you have both TensorFlow and TensorBoard already installed. If not, you can install them using `pip install tensorflow` and `pip install tensorboard`, respectively.
