尝试在 Kaggle 中加载模块 pynrrd 时出现导入错误

Question

对不起，这是一个简单的问题，但我是 Python 的新手。我正在尝试在 Kaggle 中加载模块 "pynrrd"。我收到导入错误，我不确定为什么。

这是我正在测试的代码：

# 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

错误信息如下：

     14 import scipy.misc

ImportError: No module named 'pynrrd'

PS：我也尝试过使用 nrrd 而不是 pynrrd，但这也不起作用

您可能没有通过设置允许互联网

内核右侧

点击设置
将互联网切换为 "on"

您还会发现一个从设置安装软件包的选项

应该这样导入

import nrrd
