Interesting, but you are installing r-rcpp: 0.12.17-r341h9d2a408_1 conda-forge so 0.12.17. Is there anything else on your system that infers with it?

I'm definitely calling R installed in the test conda environment.

hmmm... what am I missing?

nick-youngblut commented 6 years ago

My base conda env doesn't have Rcpp installed at all, but Rcpp (v0.12.14) will still load in an R session running from the base conda env

nick-youngblut commented 6 years ago

I checked .Libpaths(), and it appears that Rcpp is being loaded from an R install in my home directory. I changed my libpaths to just the conda install libpath. That fixed the issue, and I can now load dplyr correctly. This has never happened with my conda install previously, so I'm really surprised that it happened here. I should have checked .Libpaths() prior to posting this issue.

I still wonder why Rcpp defaulted to the version outside of my conda env even though Rcpp was installed in the conda env.

bgruening commented 6 years ago

That is an R issue, afaik. R by default looks into your HOME directory. Nothing conda can do here I think. Or we patch R to not do so?

nick-youngblut commented 6 years ago

It's weird though that my older conda install (conda 4.3.29 with R 3.3.2) doesn't include my home directory R install in the libPaths, but my newer version of conda (conda 4.5.9 with R 3.4.1) does. So the old version of conda + R is not looking in my HOME directory. Why should R installed in a conda env look into a HOME directory? I thought the whole point of conda envs was to isolate the software in the envs.

bgruening commented 6 years ago

All I know is that this is an R thing. Python does not have this problem.

nick-youngblut commented 6 years ago

OK. It does appear like a potential big issue if R is looking outside of the conda env. This could reduce the reproducibility of conda envs.

Any ideas on the best way to permanently remove my HOME R install libPath from the conda R libPaths? Permanently adding to the libPaths seems easier than permanently removing a specific libPath.

nick-youngblut commented 6 years ago

I tried downgrading r-base from R 3.4.1 to R 3.3.2. For R 3.3.2, my libPaths just includes the conda env, and not my HOME R install, so it's just the newer versions of r-base that look into the HOME directory for an R install.

nick-youngblut commented 6 years ago

I moved my HOME R install (instead of completely removing it), and all of my conda environments that use R 3.4.1 seem to have been relying on my HOME R install to some extent. So moving my R install seems to have broken all of my conda environments (at least for loading R packages), and this means that my conda envs were not fully isolated and thus they cannot be fully reproduced with a yaml file of the packages in the environment. I'm just glad I didn't completely remove my HOME dir R install...

jdblischak commented 6 years ago

Why should R installed in a conda env look into a HOME directory? I thought the whole point of conda envs was to isolate the software in the envs.

@nick-youngblut Yes, it is super frustrating that conda does not isolate itself by default. That is what everyone expects it to do, so usually the errors are more subtle. For example, one of your collaborators can install your conda environment defined by an environment.yaml file, but still be using their local R packages to perform the analysis.

See https://github.com/conda-forge/r-base-feedstock/issues/37 for an extended discussion. Unfortunately the core conda team is not overly interested in fixing this, so I don't see anything changing anytime soon. It's a shame because this is a serious weakness.

All I know is that this is an R thing. Python does not have this problem.

@bgruening Not true. conda will also use user-installed Python packages over conda packages. It's just that it is less common for Python users to have user-installed packages compared to R users due to differences in pip and install.packages(). Unlike conda, venv does properly ignore user-level Python packages. See https://github.com/conda-forge/python-feedstock/issues/171 for discussion.

bgruening commented 6 years ago

@jdblischak this problem is only partially about packages. The problem is I still wonder why Rcpp defaulted to the version outside of my conda env even though Rcpp was installed in the conda env.. I have never seen this with Python. There are multiple ways how you can disable this behavior in Python if you want to, as linked in the thread by you.

Do you know any fancy way how we can avoid this with R? Would be cool to know as there are many users having problems with this.

@bgruening That error is completely from a package path issue. The R user library was listed before the conda R library, so the wrong version of Rcpp was loaded. Python behaves the same way. If I install an old version of numpy in my Python user library and then load pandas that is installed in my conda environment, Python throws an error:

$ docker run --rm -it condaforge/linux-anvil
$ conda install -y pandas
$ python -c 'import pandas'
$ pip install --user 'numpy==1.8.2'
$ python -c 'import numpy;print( numpy.__version__)'
1.8.2
$ python -c 'import pandas'
Traceback (most recent call last):

ImportError: this version of pandas is incompatible with numpy < 1.9.0
your numpy version is 1.8.2.
Please upgrade numpy to >= 1.9.0 to use this pandas version

There are multiple ways how you can disable this behavior in Python if you want to, as linked in the thread by you.

Sure, there are also ways to get around it in R. But the point is that this requires manual intervention. And it also requires that users understand that their conda environments are not isolated from their user installation.

Do you know any fancy way how we can avoid this with R? Would be cool to know as there are many users having problems with this.

The solution analogous to Python setting export PYTHONNOUSERSITE=True would be to define R_LIBS_USER="" in ~/.Renviron. But both of these options are quite suboptimal. A user will likely want to be able to load the user packages when running Python or R outside of conda. Having to set and unset environment variables is tedious and error-prone.

But I think that conda should handle this by itself (just like venv). My proposed solution is to add a patch to r-base so that a conda-installed R ignores the default user library on that OS https://github.com/conda-forge/r-base-feedstock/issues/37#issuecomment-379859377. It's not fool-proof, but it will solve the most common problem.

bgruening commented 6 years ago

From a normal Ubuntu 18.04 Docker container:

bag@bag:~$ pip install --user 'numpy==1.8.2'
bag@bag:~$ python -c 'import numpy;print( numpy.__version__)'
1.8.2
bag@bag:~$ conda create -n pandas -y pandas
bag@bag:~$ conda activate pandas
(pandas) bag@bag:~$ python -c 'import numpy;print( numpy.__version__)'
1.14.3
(pandas) bag@bag:~$ python -c 'import pandas'

But I guess I completely misunderstood the problem here. Nevermind, sorry for the noise.

But I guess I completely misunderstood the problem here. Nevermind, sorry for the noise.

No need to apologize! I think it is important to discuss and understand this issue with user-installed packages. It is so often over-looked, but it can cause conda users a lot of pain (e.g. this current issue).
