取决于 hs300 到底有多少数据,从什么时候开始的吧

你提到的这些应该都可以,现在明确挂掉的数据源:网易(对应 A 股指数数据,但可以用雪球代替),sina (对应 A 股实时数据),英为(对应国际市场数据)。A 股股票,指数和基金的日线数据应该没问题

最新 commit indexinfo (对应网易数据源)已实现自动重定向到 vinfo,恢复可用。新浪实时数据 api 也已修复

反爬 xalpha 层面没有特有的办法解决,只能用通用的一些办法,爬慢一点或者用 ip 代理池之类的

@zaqqwerty , @MichaelBroughton , Thanks for the reply and confirmation on the status of float64 support in tfq. I agree with you that float32 is more than enough for tasks...

你可以看下对应的 tensorflow quantum 里 MNIST 的例子(当然我觉得他的处理也不理想):https://github.com/tensorflow/quantum/blob/master/docs/tutorials/mnist.ipynb。 一些典型处理和 comment: 0. 挑选出两个数字对应图像数据,一般量子线路这边算力很弱,就选一个 qubit 测量作为输出,因此得把问题转化为二分类,比去区分数字 3 和 6. 1. 图片缩放,28\*28 太大了,一般都直接 resize 到 4\*4 了 (因此这边 resize 算法很重要,因为 MNIST 降到 4*4, 反正人是看不到数字了,就是几个色块)。。。 2....

Some updates. Firstly, some thoughts on the implementation of `partial_ratio` in https://github.com/seatgeek/fuzzywuzzy/blob/778162c5a73256745eb6ae22f925bc2dbcf7c894/fuzzywuzzy/fuzz.py#L56-L59 There is the possibility that the only `block` in `blocks` is of the form `(len(shorter), len(longer), 0)`, i.e....

I believe there are many function primitives that the implementation using placeholder for v would fail. For example, by using the exactly the same code as shown by @mattjj with...

Indeed, jitting a large MPS circuit would require longer times than a plain Circuit, the jitting time varies significantly for different backend (jax vs. tf) or different hardware (cpu vs....
