dill能记住一个类使用的库吗?

dill 为了腌制它,当我解开它时,我找不到图书馆:

import dill
from sklearn.metrics.cluster import adjusted_rand_score
import pandas as pd
import random
class Test1():
    def __init__(self, df):
        self.genomes = df

    @staticmethod
    def percentageSimilarityDistance(genome1, genome2):
        if len(genome1) != len(genome2):
            raise ValueError('Genome1 and genome2 must have the same length!')

        is_gene_correct = [1 if genome1[idx] == genome2[idx] else 0 for idx in range(len(genome1))]

        return (1 - sum(is_gene_correct)/(len(is_gene_correct) * 1.0))

    def createDistanceMatrix(self, distance_function):
        """Takes a dictionary of KO sets and returns a distance (or similarity) matrix which is basically how many genes do they have in common."""
        genomes_df = self.genomes.copy()
        no_of_genes, no_of_genomes = genomes_df.shape
        list_of_genome_names = list(genomes_df.columns)
        list_of_genomes = [list(genomes_df.loc[:, name]) for name in list_of_genome_names]
        distance_matrix = [[distance_function(list_of_genomes[i], list_of_genomes[j]) for j in range(no_of_genomes)] for i in range(no_of_genomes)]
        distance_matrix = pd.DataFrame(distance_matrix, columns = list_of_genomes, index = list_of_genomes)


        return distance_matrix

# create fake data
df = pd.DataFrame({'genome' + str(idx + 1): [random.randint(0, 1) for lidx in range(525)] for idx in range(10)})
test1 = Test1(df)
test2 = Test2(df)

# save pickles
with open('test1.pkl', 'wb') as pkl:
    dill.dump(test1, pkl)

我成功地解开了文件,但当我试图使用其中一个方法时,它找不到 Pandas .

仅仅通过导入dill库就可以实现这一点吗?
