python with open('binary_file.bin', 'rb') as f: data_bytes = f.read() 使用numpy.frombuffer 函数将字节串转换为NumPy数组: python data = np.frombuffer(data_bytes, dtype=np.float32) 处理读取到的数据(可选): 同样,如果数据的形状不是你所期望的,可以使用 reshape 方法来调整。 返回或存储...
bin文件就是将数据按16进制形式存储的二进制文件(binary),可以使用WINHEX、Notepad++(需安装插件)等以16进制形式打开,如图用notepad++打开。 由于使用python中的read()读取二进制文件时是以字符串形式读取,且每次只能读取一个字节,十分不方便。 偶然发现可以使用numpy中的fromfile按指定格式对bin文件进行读写,方便了许...
