Ubuntu17.10下Anaconda+Spyder的ModuleNotFoundError及自动补全问题求助

Hey there, let's work through these frustrating issues you're facing. It sounds like Spyder's internal tools (variable explorer and autocomplete) aren't properly hooked into your Anaconda environment, even though your scripts can access numpy just fine. Here are the most reliable fixes to try:

1. Reset Spyder's Configuration #

Sometimes Spyder's cached settings get messed up. Let's wipe them and start fresh:

• Close Spyder completely.
• Open your terminal, activate your Anaconda base environment with conda activate base.
• Run spyder --reset to reset all Spyder preferences to default.
• Launch Spyder again via the terminal (spyder) and check if the variable explorer and autocomplete work.

2. Verify Spyder's Python Interpreter Setting #

Make sure Spyder is using your Anaconda Python, not the system's default:

• In Spyder, go to Tools > Preferences > Python interpreter.
• Select the option "Use the following interpreter" and browse to /home/my_name/anaconda3/bin/python.
• Click "Apply" and restart Spyder.

3. Update Spyder & Its Kernels #

Version mismatches between Spyder and its backend kernels are a common culprit:

• In your terminal (with Anaconda environment activated), run:

  conda update spyder spyder-kernels
  

• This ensures Spyder and its underlying execution layer are in sync, which often fixes autocomplete and variable explorer glitches.

4. Reinstall IPython & Kernel Components #

If the issue persists, refreshing the IPython kernel might help:

• Run these commands in your Anaconda terminal:

  conda install ipython ipykernel --force-reinstall
  

• Restart Spyder's kernel (click the restart button in the console toolbar, or go to Consoles > Restart kernel).

5. Launch Spyder Directly from Anaconda Terminal #

Ubuntu's application menu might launch Spyder without loading your Anaconda environment variables. Instead:

• Open a terminal, activate your Anaconda environment (conda activate base).
• Start Spyder with spyder.
• This ensures Spyder inherits all the environment paths from Anaconda, so its tools can find numpy and other packages.

Give these steps a try in order—most folks fix this with the first or second step. Let me know if you still run into issues!
