花了几个小时后，我意识到也许 PyQt-Fit 仅适用于 python 2.7，然后我使用 python 2.7 创建了一个 conda 环境并创建了一个内核

//This is for conda to support switching kernels
conda install nb_conda
conda create -n py27 python=2.7
conda activate py27
//install PyQt-Fit
pip install -I path.py==7.7.1
pip install git+https://github.com/Multiplicom/pyqt-fit.git
// This is needed for Jupyter Notebook connecting with new kernel
pip install pypiwin32
//Make sure you are at the same directory as the py27 env, for example, C:Anaconda3envspy27
//Create a new kernel
conda install notebook ipykernel
ipython kernelspec install-self
//now run jupyter notebook

一些有用的链接帮助我解决问题。

Jupyter 在哪个 conda 环境中执行？
