報錯：ipython 6.5.0 has requirement prompt-toolkit<2.0.0,>=1.0.15, but you'll have prompt-toolkit 2.0.15 which is incompatible.

pip install imagededup 時，報錯：ipython 6.5.0 has requirement prompt-toolkit<2.0.0,>=1.0.15, but you'll have prompt-toolkit 2.0.15 which is incompatible.

原因： setuptools 版本太高

解決方法：

conda install -c conda-forge prompt_toolkit==1.0.15

（上面1.0.15可改范圍1.0.15 ~2.0.0（包含1.0.15）間任意版本）
