Hi @lhelontra , you did great work. I try your tensorflow-1.5.0-cp35-none-linux_armv7l.whl in fresh 2018-03-13-raspbian-stretch-lite. Installation progress is work like a charm. But, when I'm importing tensorflow, there is an error, here the log:

During handling of the above exception, another exception occurred:

ImportError:
Importing the multiarray numpy extension module failed.  Most
likely you are trying to import a failed build of numpy.
If you're working with a numpy git repo, try `git clean -xdf` (removes all
files not under version control).  Otherwise reinstall numpy.

Original error was: libf77blas.so.3: cannot open shared object file: No such file or directory

And I found the solution after doing search in google, for libf77blas.so.3, I have to install ATLAS,

sudo apt-get install libatlas-base-dev

Now, no error when importing tensorflow.

Thank you.

i'm glad help you. Blas dependency is of numpy package.
