Jupyter notebook因在命令行中工作的代码而失败

Question

我正在使用以下repo自述文件中所述的命令：

https://github.com/aminnayebi/HesBO/tree/master/BLOSSOM

即：

! python blossom_run.py Hartmann6 100 6 6 1 1

在命令行或jupyter笔记本中执行时，如上面带有“！”的一行它起作用了

但是，如果我从blossom_run.py复制代码，并给它提供相同的参数，那么经过几次迭代之后，它就会失败

import gpbo
from BLOSSOM.embd_functions import *
import numpy as np
import time
import logging
import pickle
import sys

path ='/home/XXX/HesBO/BLOSSOM/blossom_results'

test_func     = 'Hartmann6'
total_itr     = 99
low_dim       = 6
high_dim      = 6
init_n        = 1
rep = job_id  = 1
noise_var = s = 0

bx_size       = 1


act_var      = np.arange(high_dim)
high_to_low  = np.random.choice(range(low_dim), high_dim)
sign         = np.random.choice([-1, 1], high_dim)

f = Hartmann6(act_var, high_to_low, sign=sign, bx_size=bx_size, noise_var=noise_var)

file_name=test_func+'_blossom_d'+str(low_dim)+'_D'+str(high_dim)+'_rep_'+str(rep)+'.csv'
C=gpbo.core.config.eimledefault(f, low_dim, total_itr, s, path, file_name)

if noise_var>0:
    file_name_params = 'blossom_results/param_'+ test_func +'_blossom_d'+str(low_dim)+'_D'+str(high_dim)+'_rep_'+str(rep)
    pickle.dump([high_to_low, sign], open(file_name_params, 'wb'))

上面的代码写在Jupyter笔记本中，经过几次迭代后失败，并返回以下错误：

--------------------------------------------------------------------------- TypeError Traceback (most recent call last) in ----> 1 out = gpbo.search(C)

TypeError: an integer is required (got type OutStream)

我还尝试将上面的相同代码放在python文件中，并在命令行中尝试python文件，因此我确信代码中没有bug，只是在Jupyter笔记本而不是终端中运行它有些奇怪

有解决办法吗
