无法在另一个jupyter笔记本中导入模块

Question

我有两个jupyter笔记本，第一个名为friedman_1.ipynb，我定义了一个类。在第二个jupyter笔记本中，我可以毫无错误地导入它。但是，我在调用类方法时出错。见下文。谢谢你的帮助

class Friedman1Test:
    """This class encapsulates the Friedman1 regression test for feature selection
    """

    VALIDATION_SIZE = 0.20
    NOISE = 1.0

    def __init__(self, numFeatures, numSamples, randomSeed):
        """
        :param numFeatures: total number of features to be used (at least 5)
        :param numSamples: number of samples in dataset
        :param randomSeed: random seed value used for reproducible results
        """

        self.numFeatures = numFeatures
        self.numSamples = numSamples
        self.randomSeed = randomSeed

在第二个jupyter笔记本中，我试图导入模块并调用其类方法，然后我得到了一个错误

from ipynb.fs.full.friedman_1 import *

# create the Friedman-1 test class:
friedman = friedman_1.Friedman1Test(NUM_OF_FEATURES, NUM_OF_SAMPLES, RANDOM_SEED)
friedman

---------------------------------------------------------------------------

      1 # create the Friedman-1 test class:
----> 2 friedman = friedman_1.Friedman1Test(NUM_OF_FEATURES, NUM_OF_SAMPLES, RANDOM_SEED)
      3 friedman

NameError: name 'friedman_1' is not defined

Answer 1

您已经将所有函数和类导入笔记本。直接尝试下列方法

from ipynb.fs.full.friedman_1 import *

friedman = Friedman1Test(NUM_OF_FEATURES, NUM_OF_SAMPLES, RANDOM_SEED)
friedman

Answer 2

试试这个

from ipynb.fs.full.friedman_1 import *

# create the Friedman-1 test class:
friedman = Friedman1Test(NUM_OF_FEATURES, NUM_OF_SAMPLES, RANDOM_SEED)
friedman

当您使用星号时已经导入了类，您只需要直接调用类构造函数
