I am having an import error while trying to load the module pynrrd in Kaggle

Question

Excuse me if this is a simple question, but I'm new to Python. I'm trying to load the module "pynrrd" in Kaggle. I am getting import errors, I'm not sure why.

Here is the code I'm testing:

# Required modules
import numpy as np 
!pip install pynrrd
import matplotlib.pyplot as plt
import matplotlib
import tensorflow as tf
import time
import os
import sys
import pydicom
import pynrrd
import scipy.ndimage
import scipy.misc
import pickle
import random
import skimage
%matplotlib notebook

if sys.version_info[0] != 3:
    raise Exception("Python version 3 has to be used!")

print("Currently using")
print("\t numpy ", np.__version__)
print("\t scipy ", scipy.__version__)
print("\t matplotlib ", matplotlib.__version__)
print("\t tensorflow ", tf.__version__)
print("\t pydicom ", pydicom.__version__)
print("\t nrrd ", nrrd.__version__)
print("\t skimage ", skimage.__version__)

np.random.seed(37) # for reproducibility

Here are the error messages:

ImportError: No module named 'pynrrd'

PS: I also tried nrrd instead of pynrrd but that didn't work either

Answer 1

You probably didn't allow internet from settings

On the right side of the kernel

1. Click settings
2. Toggle Internet to "on"

You'll find also an option to install packages from settings

The import should be done like this

import nrrd
