问题
I have installed scikit-surprise in Windows10.
C:\Users\Cosmos Lord>pip install scikit-surprise
Requirement already satisfied: scikit-surprise in c:\users\cosmos lord\appdata\roaming\python\python37\site-packages (1.1.0) Requirement already satisfied: joblib>=0.11 in c:\users\cosmos lord\appdata\roaming\python\python37\site-packages (from scikit-surprise) (0.14.0) Requirement already satisfied: numpy>=1.11.2 in c:\users\cosmos lord\appdata\roaming\python\python37\site-packages (from scikit-surprise) (1.17.2) Requirement already satisfied: scipy>=1.0.0 in c:\users\cosmos lord\appdata\roaming\python\python37\site-packages (from scikit-surprise) (1.3.1) Requirement already satisfied: six>=1.10.0 in c:\users\cosmos lord\appdata\roaming\python\python37\site-packages (from scikit-surprise) (1.12.0)
But I am still unable to import surprise module.
In Spyder3 kernel, the following error is shown:
import surprise
Traceback (most recent call last):
File "", line 1, in import surprise
ModuleNotFoundError: No module named 'surprise'
Whereas in IDLE(Python-32 bit), the following error is shown:
Traceback (most recent call last): File "C:/Users/Cosmos Lord/Documents/Flask Projects/New folder/aaa.py", line 1, in import surprise File "C:\Users\Cosmos Lord\AppData\Roaming\Python\Python37\site-packages\surprise__init__.py", line 3, in from .prediction_algorithms import AlgoBase File "C:\Users\Cosmos Lord\AppData\Roaming\Python\Python37\site-packages\surprise\prediction_algorithms__init__.py", line 23, in from .algo_base import AlgoBase File "C:\Users\Cosmos Lord\AppData\Roaming\Python\Python37\site-packages\surprise\prediction_algorithms\algo_base.py", line 10, in from .. import similarities as sims ImportError: cannot import name 'similarities' from 'surprise' (C:\Users\Cosmos Lord\AppData\Roaming\Python\Python37\site-packages\surprise__init__.py)
How do I import surprise? Any help would be much appreciated.
回答1:
From within Spyder kernel (console), run pip install surprise
Then restart the kernel.
It solved the problem for me

Welcome to Stackoverflow
Surprise uses Cython, which requires a C compiler to be installed on the system.
More about Cython
Installing Visual studio C++2014 could sovle this issue. Try installing Visual Studio on your machine.

I think it's because your current working environment and the environment the surprise module has been installed into are different.
回答4:
try:
pip install numpy
pip install scikit-surprise
if your problem didn't solve, then use conda forge:
conda install -c conda-forge scikit-surprise

If you are sure that you are in the right env, kindly change your IDE. I changed mine to Jupyterlab and everything started working correctly.
