I am trying to install through pip the scipy package. Running on Windows 10 64 bit simpl Python 2.7.3 no anaconda. Can you please tell what is going wrong while install package scipy?

Many Thanks in advance for your answers

Answer 1

As already mentioned, try with .whl

You should download the right file from here http://www.lfd.uci.edu/~gohlke/pythonlibs/#scipy Then cd to where you've downloaded your scipy_some_version.whl and

    pip install scipy_some_version.whl

Answer 2

You cannot just pip install scipy on Windows. Use Gohlke wheels or Anaconda.

Answer 3

Since Windows does not have any package manager analogous to that in Linux, you cannot just use pip install <packagename> , so installing one of the scientific Python distributions mentioned at Installing the SciPy Stack is preferred. However, if that is not an option, Christoph Gohlke provides pre-built Windows installers for many Python packages , including all of the core SciPy stack, which work extremely well.

Answer 4

I was facing the same error and it turned out that scipy was not happy with numpy. Then I used "conda intsall scipy" and it intalled the required version without any error.

For anyone using windows anaconda installation is strongly recommended. If any old version of python is required then one can create virtual env and install the required version of python.
