Python os.remove(filename) 抛出错误 "already being used by temp"

Question

我目前的代码是

import os
import pickle
import tempfile

# Pickle on HIGHEST_PROTOCOL breaks on Python 3.6.5
_PICKLE_PROTOCOL = 4
#CHANGED FROM 2 TO 4 TO ACCOMODATE VERSION, DONE BY USER


def _pickle_iterable(filename, iterable):
    with open(filename, 'wb') as pickle_fh:
        pklr = pickle.Pickler(pickle_fh, _PICKLE_PROTOCOL)
        for entry in iterable:
            pklr.dump(entry)
            pklr.clear_memo()


def _open_pickle(filename):
    return open(filename, 'rb')


def _unpickle_iterable(pickle_fh):
    with pickle_fh:
        unpklr = pickle.Unpickler(pickle_fh)
        try:
            while True:
                yield unpklr.load()
        except EOFError:
            pass


def file_buffered_tee(iterable, n=2):
    _,  filename = tempfile.mkstemp()
    try:
        _pickle_iterable(filename, iterable)
        return tuple(_unpickle_iterable(_open_pickle(filename)) for _ in range(n))
    finally:
        os.remove(filename)

os.remove(filename) 给出错误

PermissionError: [WinError 32] The process cannot access the file because it is being used by another process: 'C:\\Users\\s%username%\\AppData\\Local\\Temp\\tmpaoos53ie'

我不知道如何修复它，我从中提取的 GitHub 存储库已存档，我无法打开另一个问题请求。
我要回到 stackoverflow，在我见过的其他任何地方我都找不到适用的答案，虽然我认为我理解代码，但我一直遇到错误，哈哈
任何帮助表示赞赏!谢谢!
编辑 1:忘记导入...愚蠢的错误
编辑 2:我省略了代码，因为我认为它不需要。谢谢大家的耐心 :P
编辑3:回溯:

line37, in file_buffered_tee:

os.remove(filename)

PermissionError: [WinError 32] The process cannot access the file because it is being used by another process: 'C:\\Users\\%username%\\AppData\\Local\\Temp\\tmp*xxxxxxx*'

编辑 4: 显然同样的问题正在发生 here ，但是它完成了答案所说的所有事情，但返回了相同的错误......仍然没有在这里回答并且仍然很困惑。文档也没有帮助

您可以告诉 tempfile 在关闭时删除文件。这样，当您关闭文件时，该文件将被自动删除。
这可能对您有帮助:https://docs.python.org/3/library/tempfile.html
tempfile.NamedTemporaryFile(mode='w+b', buffering=None, encoding=None, newline=None, suffix=None, prefix=None, dir=None, delete=True , *, errors=没有任何)
delete=True 参数就是你要找的。现在使用 tempfile 通过 file.close() 关闭文件
