【已经解决】TypeError: read_img() missing 1 required positional argument: ‘filename‘

前两把读取遥感数据、存储遥感数据函数写成了一个类；然后再去调用这个类，出现了这个问题（TypeError: read_img() missing 1 required positional argument: 'filename'）：

后来查询了一下，类需要实例化，完整代码如下：

from classIMAGE import IMAGE
import numpy as npimage = IMAGE()   #实例化类的对象
# proj, geotrans, data1, row, column ,band=IMAGE.read_img(r"F:\ProfessionalProfile\DataRelevant\Landsat2017\LC08_L1TP_134036_20170808_20170813_01_T1\LC08_L1TP_134036_20170808_20170813_01_T1_B4.tif")
# proj, geotrans, data2, row, column ,band=IMAGE.read_img(r"F:\ProfessionalProfile\DataRelevant\Landsat2017\LC08_L1TP_134036_20170808_20170813_01_T1\LC08_L1TP_134036_20170808_20170813_01_T1_B3.tif")
# proj, geotrans, data3, row, column ,band=IMAGE.read_img(r"F:\ProfessionalProfile\DataRelevant\Landsat2017\LC08_L1TP_134036_20170808_20170813_01_T1\LC08_L1TP_134036_20170808_20170813_01_T1_B2.tif")
proj, geotrans, data1, row, column ,band=image.read_img(r"F:\ProfessionalProfile\DataRelevant\Landsat2017\LC08_L1TP_134036_20170808_20170813_01_T1\LC08_L1TP_134036_20170808_20170813_01_T1_B4.tif")
proj, geotrans, data2, row, column ,band=image.read_img(r"F:\ProfessionalProfile\DataRelevant\Landsat2017\LC08_L1TP_134036_20170808_20170813_01_T1\LC08_L1TP_134036_20170808_20170813_01_T1_B3.tif")
proj, geotrans, data3, row, column ,band=image.read_img(r"F:\ProfessionalProfile\DataRelevant\Landsat2017\LC08_L1TP_134036_20170808_20170813_01_T1\LC08_L1TP_134036_20170808_20170813_01_T1_B2.tif")data = np.array((data1,data2,data3), dtype=data1.dtype)  # 按序将3个波段像元值放入
# dataWrite=IMAGE.write_img(r'F:\ProfessionalProfile\DataRelevant\Landsat2017\zcs432.tif', proj, geotrans, data)
dataWrite=image.write_img(r'F:\ProfessionalProfile\DataRelevant\Landsat2017\zcs432.tif', proj, geotrans, data)

解决方法：image=IMAGE()实例化对象。

最后对比一下：左侧是Python合成后的，右侧是landsat下载的。
