Kears import error with torch backend

[JacksonZhu90]

Hi,

I was trying to use keras 3 with torch. But when I try to import keras, it shows "No module named 'tensorflow'". I do not use tensorflow here. The torch version I am using is 2.1.2

import numpy as np import os os.environ["KERAS_BACKEND"] = "torch" import torch import matplotlib.pyplot as plt import keras

Hi,

I was able to run the code without any error, Make sure you install the latest Keras and torch with

!pip install -U keras
!pip install -U torch

Below import is working fine.

import numpy as np
import os
os.environ["KERAS_BACKEND"] = "torch"
import torch
import matplotlib.pyplot as plt
import keras

Attaching the Gist here for reference.
