Re: [cx-oracle-users] anaconda python 3.5 + windows 7 + cx_Oracle 5.2?

[Codiga, D. <Dan...@mw...>]

To be a little more complete regarding my final comment, ...

When I create the environment using python 3.4, it appears that cx_Oracle 5.2 has been installed successfully (according to Anaconda Navigator, at least). Then when I try "import cx_Oracle" the problem is not exactly that it can't find the win32 file; the error message is this:

ImportError: DLL load failed: %1 is not a valid Win32 application.

Subject: anaconda python 3.5 + windows 7 + cx_Oracle 5.2?

>From what I have read in the documentation, it looks like I should be able to install anaconda python 3.5 on my windows 7 64-bit PC and include cx_Oracle 5.2 in a conda virtual environment.

However I am encountering problems in trying.

( Previously I was using Anaconda python 2.7 with cx_Oracle 5.1.2 in a conda environment without trouble. I mention this because it seems possible that my problems are associated with not fully/successfully uninstalling cx_Oracle 5.1.2? Just a thought.)

Anyway I do a clean wipe of python from my system and then install Miniconda (64 bit windows) and all is well. I then try to create an environment "conda env create environment.yml" -- with "python=3.5" and "cx_Oracle" both listed as dependencies in the environment.yml file-- and get the "specifications were found to be in conflict" error. It says " - cx_oracle -> python 2.7*|3.4*" and " - python 3.5*".

So then, to troubleshoot a little, I try same but with "python=3.4" in the environment.yml file. The environment gets created ok. But when I try "import cx_Oracle" I get an error saying it couldn't find the win32 file.

Suggestions?
