Conda env create fails using environment.yml file.

[sorenwacker]

I exported an environment using conda env export > environment.yml.
I installed miniconda3 on a different system, updated conda, installed pip.
Then conda env create -f environment.yml -n py3

Actual Behavior

It gives me this error message:

Solving environment: failed
ResolvePackageNotFound:
  - brewer2mpl==1.4=py36_0
  - ggplot==0.9.4=py36_0

Expected Behavior

The environment should be installed with the same packages indicated in the yml file. All necessary information, such as channels, should be provided by the yml file. And it should give a warning about packages from locally installed sources. I noted that e.g. the packages pyqsar from my source system is not available on the target system. Though conda did not raise a warning.

Seems like those packages don't exist at that combination of version and build on the channels searched by your target system. I found broadening my search by eliminating build info helped. The command I used was conda env export --no-builds > environment.yml.

[sorenwacker]

Ok, I will try that. Though, I don't understand why the packages should not be available, since I also installed them at the source system.

[sorenwacker]

The error changed a bit.

conda env create -f environment.yml -n py3
Solving environment: failed

ResolvePackageNotFound:
  - brewer2mpl==1.4=py36_0

[SKalt]

That was my experience as well: fixed around half the unresolved dependencies. FWIW, my eventual fix was installing the stubborn ones via pip.

[mahboobmm]

Any updates on this? Going through the same issue.

[vv111y]

same here

[chauek]

This helped me: datitran/object_detector_app#41

[lennbo]

Had that issue and solved it by first conda update --all on the host sytem, then conda export --no-builds > env.yml and regular installation via conda env create -f env.yml on the remote machine.

Guess for me the problem was that the base env conda on remote had packages installed that were not working with the older packages on the host system.

[6Hhcy]

Does anyone here know why we have any Python packages in the top section "dependencies". It seems like it only causes problems. Why not put them all under "pip"

[TejasAvinashShetty]

I think there is a small error in https://github.com/ContinuumIO/anaconda-issues/issues/9480#issuecomment-444117929 namely that

conda export --no-builds > env.yml

should instead be written as

conda env export --no-builds > env.yml

[TejasAvinashShetty]

One could also try adding a conda channel if the said packages are not present in the default channels. E.g. qutip package appears in conda-forge channel. One can add the channel by typing the following command.
conda config --append channels conda-forge Off course one needs to replace the name conda-forge by the appropriate channel name.

[TejasAvinashShetty]

I think it also helps to remove any packages which would not be necessary to prevent conflicts. One thing that we must try is by removing the version numbers associated with the packages in the .yml file.
