mmcv读取配置文件，在windows上无法创建临时文件解决方法

报错是写入Ｃ盘的Temp没有权限，因此修改到其他目录．
在config中修改以下两个函数：

    def _substitute_predefined_vars(filename, temp_config_name):
        file_dirname = osp.dirname(filename)
        file_basename = osp.basename(filename)
        file_basename_no_extension = osp.splitext(file_basename)[0]
        file_extname = osp.splitext(filename)[1]
        support_templates = dict(
            fileDirname=file_dirname,
            fileBasename=file_basename,
            fileBasenameNoExtension=file_basename_no_extension,
            fileExtname=file_extname)
        config_file = open(filename).read()
        for key, value in support_templates.items():
            regexp = r'\{\{\s*' + str(key) + r'\s*\}\}'
            config_file = re.sub(regexp, value, config_file)
