NameError: name 'get_ipython' is not defin

问题:

I am working on Caffe framework and using PyCaffe interface. I am using a Python script obtained from converting the IPython Notebook 00-classification.ipynb for testing the classification by a trained model for ImageNet. But any get_ipython() statement in the script is giving the following error:

$ python python/my_test_imagenet.py 
Traceback (most recent call last):
  File "python/my_test_imagenet.py", line 23, in <module>
    get_ipython().magic(u'matplotlib inline')

In the script, I'm importing the following:

import numpy as np
import matplotlib.pyplot as plt

get_ipython().magic(u'matplotlib inline')

# Make sure that caffe is on the python path:
caffe_root = '/path/to/caffe/'
import sys
sys.path.insert(0, caffe_root + 'python')

import caffe

plt.rcParams['figure.figsize'] = (10, 10)
plt.rcParams['image.interpolation'] = 'nearest'
plt.rcParams['image.cmap'] = 'gray'

import os

# ... Rest of the code...

Can someone please help me to resolve this error?

回答1:

You have to run your script with ipython:

$ ipython python/my_test_imagenet.py

Then get_ipython will be already in global context.

Note: Importing it via from IPython import get_ipython in ordinary shell python will not work as you really need ipython running.

If your intention is to run converted .py file notebook then you should just comment out get_ipython() statements. The matlibplot output can't be shown inside console so you would have some work to do . Ideally, iPython shouldn't have generated these statements. You can use following to show plots:

plt.show(block=True)
