Question: 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?

Answer: 
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.
`get_ipython` is available only if the IPython module was imported that happens implicitly if you run ipython shell (or Jupyter notebook).

If not, the import will fail, but you can still import it explicitly with:

```
from IPython import get_ipython

```
