With the window searcher(Type here to search) I can have python 3.6, but not 3.5
all weird things !

With the file manager I see Python35(at C:). Not Python36. I guess all my troubles come from that. I don't know how to replace Python35 by Python36.

in interactive window, type: python -V
This will show your version

Python 3.5.4. There are months I worked with python 3.6.4. If I desire I can have a console with 3.6.4. I don'nt know how 3.5.4 came up. With the window searcher I find 3.6 but not 3.5. Many weirds ! Thanks for your help.

Did you mark of Add python 3.6 to Path under install?

If 3.5 still in path,you will need to change Environment Variables Path

Did you follow tutorial and also changed path of python 3.6?

snippsat Wrote:Here also choose Path C:\Python36

If you not change path under install it will be in path far away:
C:\Users\<username>\AppData\Local\Programs\Python\Python36

Not to be rude but you have to read what i post several times,
because in many of your post you really struggle with the most basic stuff.
Maybe easier for you to uninstall 3.5 and 3.6,then follow step exactly as i post in tutorial.

I uninstalled 3.5 and 3.6. I installed python 3.4.5; As for numpy , always python cannot find numpy. May I know if your numpy is located at C:\python35\lib\site-packages ?

yet first line of traceback says

Error:

python point correct to 3.6.5.
Do this to check to check path and pip.

# Check where python is installed
C:\
λ python -c "import sys; print(sys.executable)"
C:\python36\python.exe

# Check version
C:\
λ python -V
Python 3.6.5

# Check pip
C:\
λ pip -V
pip 10.0.1 from c:\python36\lib\site-packages\pip (python 3.6)

If It look like this all is correct and what you should have if follow tutorial.

Now can you install numpy:

λ pip install numpy

Now is numpy installed to 3.6,and all you install with pip will be installed to 3.6

You are right buran. Now my pip -V gives:pip 9.0.3 from c:\program files\python36\lib\site-packages (python 3.6)
But after deleting old numpy I tried "pip install numpy", without success

You are using pip version 9.0.3, however version 10.0.1 is available.                                     
You should consider upgrading via the 'python -m pip install --upgrade pip' command.                      
                                                                                                          

You need to run cmd or same with cmder as Administrator
Upgrade pip:

C:\
λ python -m pip install --upgrade pip

Then as Administrator same install of numpy as you have.
