How do I revert to a previous package in Anaconda?
Question:
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?
Answers:
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.
You can do this in 2 ways.
1. Remove previous version and Freshly install desired version
conda remove <package_name>
Search for your package version whether it is available in conda repository.
conda search <package_name>
If it is available in the list;
conda install <package_name>=<version>
If you are going for a newer version, it may not be available. Then go for pip install <package_name> pip packages work fine with Anaconda distribution but they encourage using conda.
2. Install by downgrading package
Search for package availability
conda search <package_name>
conda install <package_name>=<version>
It may ask you to downgrade some dependencies. (optional)
Type y and hit enter.
