If I do
conda info pandas
I can see all of the packages available.
I updated my
pandas to the latest this morning, but I need to revert to a prior version now. I tried
conda update pandas 0.13.1
but that didn’t work. How do I specify which version to use?
I had to use the
install function instead:
conda install pandas=0.13.1
For the case that you wish to revert a recently installed package that made several changes to dependencies (such as tensorflow), you can “roll back” to an earlier installation state via the following method:
conda list --revisions conda install --revision [revision number]
The first command shows previous installation revisions (with dependencies) and the second reverts to whichever
revision number you specify.
Note that if you wish to (re)install a later revision, you may have to sequentially reinstall all intermediate versions. If you had been at revision 23, reinstalled revision 20 and wish to return, you may have to run each:
conda install --revision 21 conda install --revision 22 conda install --revision 23
I know it was not available at the time, but now you could also use Anaconda navigator to install a specific version of packages in the environments tab.
