PIL can't read binary

[Frank Liou]

I use PIL  Image.open()

but it show  'list' object has no attribute 'open'

this is my code

class Image2():
    trans = connection.begin()
    session = Session()
    ProductId = session.query(ProductEntity.ProductId).filter(ProductEntity.CompanyId=="2").all()
    Image = session.query(ProductImageGalleryEntity).filter(ProductImageGalleryEntity.ProductId=="20").all()
    PicFromDataBase = Image[0].ProductImage
    try:
        b = Image.open(str(PicFromDataBase))
    except Exception as e:
        sad = e
