在Python 3.4中使用Odoo API导入图像

我正在编写一个脚本，以便在我的Odoo数据库中导入产品列表。除了导入图像之外，该脚本与odooapi配合得非常好。 到目前为止，我所做的是从python中的URL导入一个图像，然后在base64中对其进行编码：

    response = requests.get(image_url)
    img_obj = Image.open(BytesIO(response.content))
    buffer = BytesIO()
    img_obj.save(buffer, format="JPEG")
    img = base64.encodestring(buffer.getvalue()).strip()
    try:
        base64.b64decode(img)
    except TypeError:
        padding = len(img) % 4
        if padding == 1:
            img = "Invalid base64 string: {}".format(img)
        elif padding == 2:
            img += b'=='
        elif padding == 3:
            img += b'='

这段代码运行得很好。但是，当我运行python代码以使用Odoo API导入它时，我得到的是：

我已尝试更正base64填充（正如您在我以前的代码中所看到的），但这不起作用。有人知道我如何解决这个问题吗？ 它可能来自我的脚本，它在Python 3.4中，而Odoo在Python 2.7中

谢谢，

好的，我终于找到问题了。 正如我想知道的，问题来自于Python 3.4和Python 2.7之间的差异。 我只是在Python2.7中运行我的代码，只是更改了一些库导入，现在，它的工作：-）
