python-lmdb使用log

1

with open(imagePath, 'r') as f: imageBin = f.read()

错误：

imageBin = f.read() UnicodeDecodeError: 'gbk' codec can't decode byte 0xff in position 0: illegal multibyte sequence

解决方法： open文件时按字节打开,参数加入 ‘b’

with open(imagePath, 'rb') as f: imageBin = f.read()

2写入的信息都需要编码为二进制形式

imageKey = ('image- d' % cnt).encode() labelKey = ('label- d' % cnt).encode() cache[imageKey] = imageBin cache[labelKey] = label.encode()
