I have recently upgraded several packages, like pandas, sklearn, in my python environment, via pip, and am now getting very different results. How can I retrieve a history of recent upgraded packages so I can try to track down why I am seeing a huge difference in accuracy in my model?
I have tried this answer:
import pip, os, time
for package in pip.get_installed_distributions():
print ("%s: %s" % (package, time.ctime(os.path.getctime(package.location))))
But this seems to be giving me only the installed time, not the update time.
