I am trying to set up an arcpy friendly environment for use with ArcMap10.4. Our code uses Python2.7 and my current installation of Python is 3.
Here are the steps I've taken so far.
Followed Arcpy installation with anaconda.
Created an environment within conda, forcing to 32bit.
(base) C:\Users>set CONDA_FORCE_32BIT=1
(base) C:\Users>conda create -n arcpy104 python=2.7.10 numpy=1.9.2 matplotlib=1.4.3 pyparsing xlrd xlwt pandas scipy ipython ipython-notebook ipython-qtconsole
(base) C:\Users>conda activate arcpy104
(arcpy104) C:\Users>spyder
Opens as Python3.7
