ImportError: Cannot import name check_build from partially initialize module 'sklearn'

Question

I'm getting the following error while trying to import from sklearn

from pandas import read_csv
from numpy import mean
from matplotlib import pyplot
from sklearn.metrics import mean_squared_error

Here is the error:

ImportError                               Traceback (most recent call last)
<ipython-input-1-c57768f466c0> in <module>
      2 from numpy import mean
      3 from matplotlib import pyplot
----> 4 from sklearn.metrics import mean_squared_error

ImportError: cannot import name '__check_build' from partially initialized module 'sklearn' (most likely due to a circular import) (C:\Users\user\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.8_qbz5n2kfra8p0\LocalCache\local-packages\Python38\site-packages\sklearn\__init__.py)

Does this answer your question? [ImportError in importing from sklearn: cannot import name check\_build](https://stackoverflow.com/questions/15274696/importerror-in-importing-from-sklearn-cannot-import-name-check-build) — , Apr 08 '20 at 17:33
In any case, `from numpy import mean` is a terrible idea. Use `import numpy as np` and `np.mean()` instead. — desertnaut, Apr 08 '20 at 17:51

I was having the same problem, but i managed to solve it..Worth your time to try: Please follow the sequence. in CMD,

- a) pip uninstall numpy
- b) pip uninstall scipy
- c) pip uninstall matplotlib
- d) pip uninstall sklearn
- e) pip uninstall scikit-learn

Then,

- a) pip install numpy
- b) pip install scipy
- c) pip install matplotlib
- d) pip install sklearn
- e) pip install scikit-learn

Follow 1a) to 1e) , then 2a) to 2e).
