使用Spyder导入TensorFlow报错求助：NameError: name 'python' is not defined

Hey there, let's work through this TensorFlow import issue you're hitting after getting Keras and Theano sorted out. That NameError: name 'python' is not defined typically crops up when there's an environment path conflict or a corrupted TensorFlow installation caused by your recent package fixes. Here are some practical steps to resolve it:

• Double-check your active environment
  If you're using a virtual environment (conda, venv, etc.), ensure you're in the same one where TensorFlow worked originally. For conda users, run this in your terminal:

  conda activate your_environment_name
  

  Launch Spyder directly from this activated environment—sometimes the standalone Spyder installation picks up the wrong system-wide interpreter instead of your virtual env.

• Reinstall TensorFlow cleanly
  Your Keras/Theano fixes might have overwritten or broken TensorFlow's dependencies. Start by uninstalling it completely:

  # For pip users
  pip uninstall tensorflow -y
  
  # For conda users
  conda uninstall tensorflow -y
  

  Then reinstall the version that was working for you (or the latest stable release if you don't mind updating):

  # Pip example with specific version
  pip install tensorflow==2.15.0
  
  # Conda example
  conda install tensorflow==2.15.0
  

• Fix Spyder's Python interpreter setting
  Open Spyder and go to Tools > Preferences > Python interpreter. Make sure the selected interpreter points to the python executable in your activated environment (look in the Scripts folder on Windows, bin on macOS/Linux). Save the setting and restart Spyder—this ensures Spyder uses the environment where you just reinstalled TensorFlow.

• Check for conflicting packages
  Run this command in your terminal to list all installed packages and spot any duplicates or conflicts:

  pip list
  

  Look for multiple versions of TensorFlow, Keras, or Theano. If you find any, uninstall the extra versions to clean up your environment.

• Test in a terminal first
  Before opening Spyder, verify TensorFlow works in your activated environment by running:

  python -c "import tensorflow as tf; print(tf.__version__)"
  

  If this works, the problem is definitely with Spyder's interpreter setup. If it still fails, create a fresh virtual environment, install TensorFlow first, then add Keras and Theano to avoid conflicts.
