有人知道发生了什么吗？我正在尝试遵循以下视频中的结构： https://www.youtube.com/watch?v=QjZdvNgYl3s&t=731s

任务是为qiskit做贡献！

非常感谢您

Answer 1

问题来自scikit-quant 中的依赖项。解决此问题的最直接方法是安装以前 (0.7) 版本的 scikit-quant 而不是当前的 0.8，因为 Qiskit 似乎与它兼容：

pip install 'scikit-quant==0.7'

Answer 2

用SQNomad 0.2.1 修复；感谢 luciano 的报告。

但它现在也成为scikit-quant 的可选组件，如果需要，可以与scikit-quant[NOMAD] 一起安装。它是一个相当大的 C++ 库，需要将依赖 Python 的部分和独立于 Python 的部分分开，以防止产生巨大的轮子，这样安装会更容易，并且可以恢复它的可选状态。

在任何情况下，所有优化器都可以独立安装和使用（例如，对于 NOMAD，使用 python -m pip install SQNomad）。
