当我尝试使用下面的user_name和Item dict运行下面的函数时，出现以下错误。我只提供了Item dict的示例，因为它非常大。这是一种压缩的numpy图片数据格式。我是队列和线程程序包的新手。我正在Mac上工作，并从jupyter笔记本中的某个单元运行代码，这可能是问题之一吗？我还从更大的dict中采样了Item dict，因此原始dict中的某些dict键会丢失。对于造成此错误的原因的任何提示将不胜感激。

They have stretched so badly that I was walking awkwardly. I'd have had better control with flipflops and more comfort being barefoot. In addition, the footbed felt hard and lumpy as the day went on. Also, the red color of the insole on the other pair stains kneehighs, and it doesn't wash out.I tried on 2 other pair of Easy Street sandals/shoes recently and found them to fit as poorly as these. Easy Street is not a brand I can wear.May 7: I bought two pairs of this sandal, one red, one blue. The size I wanted (7N) was not available in both colors, so I ended up ordering one 6.5M and one 7N. Strangely, the 6.5 is actually slightly longer than the 7. The M is a tiny fraction wider than the N, but both are loose. They are not uncomfortable, but I would be much happier if they were not so wide. For the price, they are okay, but I will not buy more. They just feel sloppy as I walk.",

But they are not just too small, they are far, far too small. I measured them sole-to-sole against 3 other pairs of shoes of the same size, and they are not even close to the same length. I think they are mismarked. Perhaps they are a 5.5 or a 6. They had obviously been tried on and returned before I got them. The packaging and stuffing was neat, but disarranged (stuffing out of the shoes). Somebody else might have had the same experience with these shoes. I'll be returning them, too.",

They were very comfortable almost all day at work, especially the toe box, which often is too pointed for me. After about 7 hours the tiny little places that rubbed prompted me to change shoes, but I really think one more wearing will soften those little places. Who knows, after two more wearings I may raise the rating to 5 stars.They fit in almost all respects. They are a tiny bit tight across where the elastic is, but I think they'll stretch. I'm okay with how they look, and I really like the color. They aren't as cute on, in my opinion, as they are in the picture, but they are still fine. It's difficult to summarize. I guess they are middle-of-the-road. Nice enough to keep, but not quite as nice as I'd hoped. I love Clarks and have several pairs of shoes and boots, so I will hope for the best with this pair. If I could, I'd give 3.5 stars.",
