I am working on issue #7949, and need to use "-3" switch while running python 2.7 for my tests. python -3 -c "import numpy as np; np.test()"
Several errors are reported and all all of them are DeprecationWarnings, which is ok. (https://travis-ci.org/njase/numpy/jobs/162733502)
*But now these errors must be either fixed or skipped. This is where I am facing problem. Pls suggest:*
1. *Identify that python was invoked with -3 and skip these cases*: There seems no way to know if python was invoked with -3 sys.argv only reports about "-c" and ignores other switches
2. *Fix these issues:* All of them are about deprecated APIs and new APIs have been introduced in python 3. Since I am using python 2.x, I don't see a way to fix them
What to do?
