安装tensorflow-gpu后导入keras报错：No module named 'keras'求助

Hey there! I totally get how frustrating it is when you're setting up your first deep learning environment and hit a roadblock like this. Let's break down what's going on and how to fix it quickly.

Why This Happens #

Starting with TensorFlow 2.0, Keras is no longer a separate standalone library you need to install independently. It's fully integrated into TensorFlow as the tf.keras module. The tensorflow-gpu package you installed already includes the official Keras implementation—you just don't need to import it as a separate keras module anymore.

The Easy Fix #

Instead of running:

import keras

Use the TensorFlow-integrated version of Keras with either of these imports:

# Option 1: Import the entire keras module from tensorflow
from tensorflow import keras

# Option 2: Alias it for shorter usage (matches standalone keras workflow)
import tensorflow.keras as keras

After switching to this import, you can use all Keras functionality exactly like you would with the standalone package—for example, keras.models.Sequential() or keras.layers.Dense() will work perfectly.

Bonus: Verify Your Setup Works #

To make sure everything is running smoothly, run these quick checks:

import tensorflow as tf
from tensorflow import keras

# Check TensorFlow version
print(tf.__version__)
# Check integrated Keras version
print(keras.__version__)

# Test a tiny model to confirm basic functionality
model = keras.Sequential([keras.layers.Dense(10, input_shape=(1,))])
model.compile(optimizer='adam', loss='mse')
print("Model compiled successfully!")

A Quick Heads-Up About tensorflow-gpu #

Just a note: The tensorflow-gpu package has been deprecated in newer TensorFlow versions (since TensorFlow 2.10 on Windows, and earlier for other OS). Now, the standard tensorflow package automatically includes GPU support if your system has the correct CUDA/cuDNN setup. If you ever reinstall or update your environment, use pip install tensorflow instead of tensorflow-gpu.
