I'm receiving the following warning on issuing the 'conda update --all' command:

Warning: 2 possible package resolutions (only showing differing packages):
- defaults::quandl-3.2.0-py36h30f7a5e_0, defaults::requests-2.14.2-py36_0
- defaults::quandl-3.1.0-py36_0, defaults::requests-2.18.4-py36h4371aae_1

Is this as a result of a bug, or is there a way to resolve it?

Can you provide the output of conda info?

It's possible we have a packaging issue here. It appears that @nehaljwani built quandl-3.2.0, so hopefully he can chime in here with some additional context.

I wasn't able to find the quandl recipe at https://github.com/AnacondaRecipes.

However, lookin in https://repo.continuum.io/pkgs/main/linux-64/repodata.json, I'm seeing

    "quandl-3.2.0-py36h3624063_0.tar.bz2": {
      "build": "py36h3624063_0",
      "build_number": 0,

        "numpy >=1.8",
        "pandas >=0.14",
        "python >=3.6,<3.7.0a0",
        "python-dateutil",
        "requests >=2.7.0,<2.18",
        "six"
      ],
      "license": "MIT",
      "md5": "18f3df76b2ce79925ee107ebf7a7b743",
      "name": "quandl",
      "sha256": "805679b63389b3a17eb5b5107405c5ca48f92f33fe9f59afa763728252b6cf42",
      "size": 39252,
      "subdir": "linux-64",
      "timestamp": 1509567355946,
      "version": "3.2.0"
    },

and in comparison, from https://repo.continuum.io/pkgs/free/linux-64/repodata.json

    "quandl-3.1.0-py36_0.tar.bz2": {
      "build": "py36_0",
      "build_number": 0,
      "date": "2017-03-13",
      "depends": [
        "inflection >=0.3.1",
        "more-itertools",
        "numpy",
        "pandas >=0.14",
        "python 3.6*",
        "python-dateutil",
        "requests >=2.7.0",
        "six"
      ],
      "license": "MIT",
      "md5": "dfdf967995d9bafafd87ffa933a1d28d",
      "name": "quandl",
      "size": 29211,
      "version": "3.1.0"
    },

So the new package adds an upper bound to the requests dependency, and that upper bound should be patched onto the other quandl packages I'm guessing.

Does anyone really know how to solve this issue with Multiple package resolutions?

@Selena-21 The numba channel seems to be giving multiple possible resolutions, removing that channel will cause this warning to go away.

I'm getting this issue. Did a conda update conda before running an update all. I get this when I try to update all on my root environment (which is python 2.7) or on an additional environment that is 3.6.

The problem is that old builds of nbconvert do not put any constraint on their pandoc version. New ones do. The solver is forced to choose between newer nbconvert or newer pandoc, and they're mathematically equivalent here. We need to fix our repo data, so that all nbconvert builds have an upper bound for pandoc.

@msarahan, Jupyter guys decided to increase the upper level of Pandoc to < 3.0, but that's still unreleased:

jupyter/nbconvert#964

Older versions should use < 2.0, I think.

conda-forge has removed the upper bound from the pandoc requirement in the nbconvert recipe, conda-forge/nbconvert-feedstock#28. I'll release a package to defaults with the same pinning.

A new nbconvert package is available in defaults which should address the mutliple solutions issue mentioned here.

Hi. Just performed a conda update --all and the following packages were downloaded and installed.
Is 'py_2' the correct build for nbconvert?

The following packages will be downloaded:

    package                    |            build
    ---------------------------|-----------------
    matplotlib-3.0.3           |   py37h5429711_0         6.6 MB

                                           Total:        18.0 MB

Now after the installation of the packages and performing another conda update --all, no longer receiving the warning.

I just reinstalled Anaconda on Win 10 and have the same problem as many above. Different to some others in my case the channel is always defaults::. I assume I have to read it top/bottom rather than left/right? Note: The problem is the same in base and environments.

Warning: 2 possible package resolutions (only showing differing packages):
  - defaults::jupyter_console-5.2.0-py37_1, defaults::prompt_toolkit-3.0.2-py_0
  - defaults::jupyter_console-6.0.0-py37_0, defaults::prompt_toolkit-2.0.9-py37done

Question: Should running any of the below lines NOT show the "package resolutions" when running the code (BEFORE), or only AFTER an update was done. I am assuming it is BEFORE, but that has not been clear. When I run the below lines I still see the package resolutions issues, so I do not execute them at the y/n junction.
conda update --strict-channel-priority --all
conda update --all

tloredo commented Jan 21, 2020

I've been experiencing this problem for several weeks after conda update conda. I've copied my conda info output below. I find this thread confusing regarding what the solution is, and whether any of these solutions are permanent/sanctioned and/or have side effects that will need to be dealt with down the road:

conda update --strict-channel-priority --all 
conda update --all [not clear if this is separate or must follow the previous one]
conda install conda=4.8 [will this require me to manually track the current version going forward?]

I'd appreciate clarification/advice on the best way forward.

The problem is that old builds of nbconvert do not put any constraint on their pandoc version. New ones do. The solver is forced to choose between newer nbconvert or newer pandoc, and they're mathematically equivalent here. We need to fix our repo data, so that all nbconvert builds have an upper bound for pandoc.

Thank you, @msarahan ! Yours was the only comment in this thread that actually explained what was happening so that I understood whether or not to worry about this. I was finding the issue with importlib, but of course almost everyone who has this issue will have it with a different package.

The truly useful answer, therefore, is to explain the underlying mechanic: there are two potential repos, each of which are equivalently "correct" because one is further ahead for one dependency and the other is further ahead for another.

In my case, I am assuming "all is good", but if I have a problem, now I know I can force the other repo to be chosen (or I can force a particular version of a dependency).

People should not "thumbs up" other complaints or problems... it challenges others in tracking down the truly useful answers like what Mike provided above.

You should go to your anaconda directory, anaconda3/pkgs and look for the resolution you want to delete, I delete low versions actually.
If you're not sure what resolution to delete make a backup of each.
