Google Foobar解决方案可在Jupyter笔记本电脑上使用，但不能在Google终端上使用

如何解决Google Foobar解决方案可在Jupyter笔记本电脑上使用，但不能在Google终端上使用

我处于Google Foobar的第3级，并且我编写的代码在Jupyter笔记本中有效，但是当我在Foobar命令行中运行它时，没有任何测试用例通过。当我在Foobar中运行它时，没有任何类型的错误，只是说答案不正确。

Doomsday Fuel
=============

Making fuel for the LAMBCHOP's reactor core is a tricky process because of the exotic matter involved. It starts as raw ore,then during processing,begins randomly changing between forms,eventually reaching a stable form. There may be multiple stable forms that a sample could ultimately reach,not all of which are useful as fuel. 

Commander Lambda has tasked you to help the scientists increase fuel creation efficiency by predicting the end state of a given ore sample. You have carefully studied the different structures that the ore can take and which transitions it undergoes. It appears that,while random,the probability of each structure transforming is fixed. That is,each time the ore is in 1 state,it has the same probabilities of entering the next state (which might be the same state).  You have recorded the observed transitions in a matrix. The others in the lab have hypothesized more exotic forms that the ore can become,but you haven't seen all of them.

Write a function solution(m) that takes an array of array of nonnegative ints representing how many times that state has gone to the next state and return an array of ints for each terminal state giving the exact probabilities of each terminal state,represented as the numerator for each state,then the denominator for all of them at the end and in simplest form. The matrix is at most 10 by 10. It is guaranteed that no matter which state the ore is in,there is a path from that state to a terminal state. That is,the processing will always eventually end in a stable state. The ore starts in state 0. The denominator will fit within a signed 32-bit integer during the calculation,as long as the fraction is simplified regularly. 

For example,consider the matrix m:
[
  [0,1,1],# s0,the initial state,goes to s1 and s5 with equal probability
  [4,3,2,0],# s1 can become s0,s3,or s4,but with different probabilities
  [0,# s2 is terminal,and unreachable (never observed in practice)
  [0,# s3 is terminal
  [0,# s4 is terminal
  [0,# s5 is terminal
]
So,we can consider different paths to terminal states,such as:
s0 -> s1 -> s3
s0 -> s1 -> s0 -> s1 -> s0 -> s1 -> s4
s0 -> s1 -> s0 -> s5
Tracing the probabilities of each,we find that
s2 has probability 0
s3 has probability 3/14
s4 has probability 1/7
s5 has probability 9/14
So,putting that together,and making a common denominator,gives an answer in the form of
[s2.numerator,s3.numerator,s4.numerator,s5.numerator,denominator] which is
[0,9,14].

To provide a Python solution,edit solution.py

Test cases
==========
Your code should pass the following test cases.
Note that it may also be run against hidden test cases not shown here.

-- Java cases --
Input:
Solution.solution({{0,0},{0,4},0}})
Output:
    [7,6,8,21]

Input:
Solution.solution({{0,1},{4,0}})
Output:
    [0,14]

-- Python cases --
Input:
solution.solution([[0,[0,4],0]])
Output:
    [7,21]

Input:
solution.solution([[0,[4,0]])
Output:
    [0,14]

我的解决方法如下：

                if original_matrix.iloc[i,j]:
                    original_matrix.iloc[i,j] = original_matrix.iloc[i,j] / sum
    return original_matrix

def create_absorption_matrix(sorted_matrix):
    count = 0
    for i in range(len(sorted_matrix.index)):
        if not(sorted_matrix.sum(axis=1).iloc[i]):
            sorted_matrix.iloc[i,i] = 1

    return sorted_matrix,count

    return denominators

def calculate_greatest_common_denominator(denominators):
    GCD = 0
    if len(denominators) == 1:
        return denominators
    else:
        for i in range(len(denominators) - 1):
            cur_GCD = np.lcm(denominators[i],denominators[i + 1])
            if cur_GCD > GCD:
                GCD = cur_GCD
    return GCD

def return_int_array(denominator,fractions):
    final_list = []
    for i in range(len(fractions)):
        if(not fractions[i].numerator):
            final_list.append(0)
        else:
            multiplier = denominator/fractions[i].denominator
            final_list.append(int(fractions[i].numerator * multiplier))
    final_list.append(int(denominator))
    return final_list

使用此代码运行任何测试用例都可以，但是每个测试在Foobar上均失败。是否存在某种格式错误？我已经检查了返回的对象类型与Foobar寻找的对象类型，它们都是int列表。据我所知，Foobar使用的是Python 2.7.13支持代码中的所有内容。我使用的库也被允许。

解决方法

我认为您应该尝试首先检查这些库（如果已安装）及其版本。 然后，您应该在实际环境中使用replit或其他工具。 最后，您的代码是否在解决方案类上？
