I would like to ask you what is the situation, that is, I will report such an error when I use snaphu to unwrap

应用 Multi-looking

def apply_multilook(product):

调用示例

if name == “main”:
# 输入干涉图产品路径（这个路径是你生成干涉图的结果路径）
interferogram_product_path = ‘/data/wangfengmao_file/aipy/output/S1A_IW_SLC__1SDV_20220110T231926_20220110T231953_041405_04EC57_103E_interferogram.dim’

# 输出路径（保存处理后的Multi-looking和Goldstein Phase Filtering产品）
output_path = '/data/wangfengmao_file/aipy/output'

# 临时路径（保存中间处理结果：Snaphu Export）
temp_path = '/data/wangfengmao_file/aipy/temp_path'

# 运行 Multi-looking、Goldstein Phase Filtering 和 Snaphu Export 处理
process_multilook(interferogram_product_path, output_path, temp_path)
