.format(mode)

`.format(mode)` is a method in Python used to format strings. The `mode` is a variable or value that you want to insert into a string. The `format()` method replaces the curly braces `{}` in the string with the value of the `mode` variable. Here's an example:

name = "Alice"
age = 25
message = "My name is {} and I am {} years old.".format(name, age)
print(message)

Output:

My name is Alice and I am 25 years old.

In this example, the `format()` method is used to insert the values of the `name` and `age` variables into the string. The curly braces `{}` act as placeholders for the values.

def calculate_bbox_score_and_save_img(image_path_name, dataset_image_path, gt_x1, gt_y1, gt_x2, gt_y2): logging.debug('dataset_image_path {}'.format(dataset_image_path)) logging.debug('image_path_name {}'.format(image_path_name)) candidates = selective_search_bbox(image_path_name) logging.debug('candidates {}'.format(candidates)) image_name = image_path_name.split('/')[-1].split('.')[0] logging.debug('image_name {}'.format(image_name)) img_read = Image.open(image_path_name) logging.debug( '{} {} {}'.format(img_read.format, img_read.size, img_read.mode))

这是一个用于计算物体框与真实物体框之间的交并比，并保存含有矩形框的图像的函数。输入参数包括图像路径、数据集图像路径、真实物体框的左上角和右下角坐标。函数首先调用selective_search_bbox函数得到候选框，然后计算每个候选框与真实物体框的交并比，并保存交并比最大的矩形框的图像到数据集图像路径下，以图像名命名。函数返回无。

该函数通常用于目标检测任务中，可以自动搜索候选框并计算交并比，从而找到最匹配的物体框，并保存图像以备后续使用。

spark .write.mode("overwrite").option("delimiter", "\t").format("com.databricks.spark.csv").option("header", "false")

这是Spark写入外部数据的一种方式。其中，mode("overwrite")表示如果文件已经存在，则覆盖原文件；option("delimiter", "\t")表示使用制表符作为分隔符；format("com.databricks.spark.csv")表示写入的文件格式为CSV；option("header", "false")表示不包含列名。
