I am installing SciPy on Windows 7 64 bit. I am using  ArcGIS 10.3 and default NumPy version 1.7.1 and I downloaded the SciPy version 1.1.0 from Python libs. After stored in the site package of Python folder When I executing the Scipy, I am getting following error.   

Earlier I installed the SciPy in the same way which I follow now, but now it's returning the error msg. 

type "copyright", "credits" or "license()" for more information.

Scrolling through the links provided by Dan Patterson‌, and some support pages I noticed this:

I do however, strongly recommend you to update to a more recent version of ArcGIS and if you can as Dan Patterson suggested install ArcGIS Pro which already has SciPy included. Follow the steps described in several blogs by Dan on how to install Spyder with ArcGIS Pro:

check that that version of scipy supports that version of numpy.  Scipy tends to be a dot version behind numpy, not the otherway around.. 

Your best bet to keep everything working is to install PRO since it contains a clean happy, gets-along version of python (3.6), numpy and scipy.

Dan Patterson‌ I have downloaded several version of Scipy i.e. 0.18, 1.1 but it's producing the same error. May I please know the compatible version of scipy with 1.7.1 Numpy version.

NumPy is currently in version 1.14.x

ArcGIS PRO uses  '1.13.3'

I don't even know what year numpy 1.7.1 was released.

BUT https://www.scipy.org/ is you want to go back... Past News on that page seems to be the spot

I have tried using the lower version of Scipy I.e 0.17.0, 0.17.1 etc, but it's producing the another error

Traceback (most recent call last):

raise ImportError(msg)
ImportError: Error importing scipy: you cannot import scipy while
being in scipy source directory; please exit the scipy source
tree first, and relaunch your python intepreter.

The message  means that you have to start python in the python folder.  You are currently located in the scipy folder and you can't import spyder that way...

Are you not using a python IDE or are you trying to run stuff  from the command prompt?  Open a python ide, load and compile and run your script from there

Hi Xander Bakker‌ Thank you. I have solved the issue by installing SciPy version 1.6 windows executable file.

glad to see that the version was found... you should still upgrade since a lot has been changed/improved in subsequent versions of all the solftware involved
