Installation error - Githubissues

Peter010103 commented 6 months ago

Hello,

I am having a bit of trouble trying to install this library.

I am using Python 3.7 on Ubuntu 22. I have previously had success working with py3nj in Ubuntu 20, but I really am not sure what the issue is.

I have installed a fortran compiler and openmp as discussed in other issue posts.

Apologies for the long build log. This is trying pip install py3nj

I looked at your error log, but honestly I have no idea about the error.

Our testing suite runs on Ubuntu 22 as well, so the OS should not be the issue. One thing I can think of is the numpy version. numpy==1.7 seems quite old. Could you try installing py3nj again after updating numpy?

DanielChaseButterfield commented 1 month ago

I had a very similar error, but I was able to resolve it. In order to prepare, I ran the following commands:

pip install meson
pip install ninja
sudo aptitude install gfortran

After doing this, and trying to install this library with the pip install py3nj, I got the following error output. Note I'm on an Ubuntu 22.04.4 LTS system:

Funnily enough, I also had the error: ```#warning "Using deprecated NumPy API, disable it with " "#define NPY_NO_DEPRECATED_API NPY_1_7_API_VERSION", but when I checked what version of NumPY I had in my python environment, it stated:

Defaulting to user installation because normal site-packages is not writeable
Requirement already satisfied: numpy in /usr/lib/python3/dist-packages (1.21.5)

This made me think that the issue was due to Meson or Ninja using a different numpy installation. Since I was operating in a conda environment, I decided to try installing numpy directly through python:

conda install numpy

After this, I was able to build the repository:

Not sure how this fixed the issue, but my theory is that installing numpy directly through conda led the build system to use the proper updated version of NumPy, instead of ignoring the pip installation to use some older numpy version installed on the computer. @Peter010103 Does this work for you?

fujiisoup commented 1 month ago

Thank you, @DanielChaseButterfield for your investigation. This should be the answer. ~Yes, we are using conda install numpy in the test suite, which does not show errors in the installation.~ I will try reproducing this symptom.

fujiisoup commented 1 month ago

Yes, we are using conda install numpy in the test suite, which does not show errors in the installation.

I noticed that our current test suite do not use conda, but just running pip install ..

Let me clarify, @DanielChaseButterfield.

Do you have more than one python environment (e.g., one in usr/bin/python3 and ~/Library/Python/3.7/site-packages )? And then while you are installing py3nj into your user python environment, Meson or Ninja picks up the numpy in the other environment?

DanielChaseButterfield commented 1 month ago

I do have multiple python environments. I have my /usr environment, and multiple conda environments. This is the python version and numpy version for each:

/usr/bin/python
Python 3.10.12
'1.21.5'

/home/dbutterfield3/miniconda3/envs/morph/bin/python
Python 3.9.19
'1.26.4'

/home/dbutterfield3/miniconda3/envs/gnn/bin/python
Python 3.11.9
'2.0.0'

/home/dbutterfield3/miniconda3/bin/python    (the base conda environment)
Python 3.12.4
ModuleNotFoundError: No module named 'numpy'

Notably, all of my installed NumPy versions are 1.21+, which doesn't seem to make sense due to the 1.7 NumPy deprecated message... But presuming that the build system was unable to see the numpy installation in my morph environment, maybe it fell back to the base conda environment. And since numpy isn't installed there, maybe one of the other packages in the base environment has an internal numpy that it ended up using? All of these are sort of wild theories... I'm not sure what happened exactly.

fujiisoup commented 1 month ago

Thank you, @DanielChaseButterfield

I assumed you have Numpy 1.7 somewhere, but it does not seem so. It is weird.

@kalekundert Do you have any idea for this issue? Meson seems like failing to find an appropriate numpy in the environment.

I believe that according to the official document meson will use the python environment which is used to run Meson,

That argument is optional, if not provided then the returned python installation will be the one used to run Meson.

So it should not matter...

fujiisoup commented 1 month ago

I am trying to reproduce this symptom in our GithubActions https://github.com/fujiisoup/py3nj/actions/workflows/test.yml but no success.

I thought it is caused by the conflict between Anaconda's environment and system environment, so I prepared an Anaconda without numpy installed, and install py3nj to this environment. Unfortunately, I didn't get the error.

kalekundert commented 1 month ago

I'm also not sure what's causing these installations to fail, but I don't think the numpy 1.7 warning is relevant. The pip output is just saying that f2py is using the old numpy API in the C code it's generating, perhaps because it hasn't been updated to generate the new API yet. It's not saying that numpy 1.7 is installed somewhere. Also, the two steps that generate this warning ([2/11] and [4/11]) both ultimately succeed.

It seems like the build fails due to the [3/11] step, which is unable to find _wigner-f2pywrappers.f. Maybe this file wasn't created for some reason, or maybe it was created in the wrong place? I don't really know what this step is supposed to do, and it succeeds on my system with no output. I looked for other errors related to this step, and this is the closest I found, but I couldn't really tell if it's relevant to our problem here.

@DanielChaseButterfield I'm curious what output the following commands produce:

$ which python
$ python --version
$ python -m venv venv
$ . venv/bin/activate
$ which python
$ python --version
$ python -m pip install --no-cache-dir -vvv py3nj

@fujiisoup The best solution to installation problems like this might be to upload binaries to PyPI. Right now PyPI has only a source distribution, so everyone who wants to use py3nj has to compile it themselves. It should be possible to use cibuildwheel to build binaries for all the most common systems on the CI server, where we already have the build working, and then upload the results to PyPI. I've done this for one of my projects, which may be useful as a reference: see here. Note that this config uses a tool called "semantic release" to automatically bump the version number, but in retrospect I'd recommend against doing that.

Just to give some background info, when pip needs to build a package like py3nj, it creates a temporary virtual environment and installs all of the necessary build dependencies there. This completely isolates the build process from any other python packages installed on the system, and makes the build process much more reliable[^1]. So if the build process were being affected by the version of any python package you have installed anywhere, that would be a pretty shocking bug in pip.

Similarly, there's no need to do pip install meson or pip install ninja before pip install py3nj. Meson is a pure python package and will automatically be installed in the build environment. Any version installed outside the build environment will be invisible to the build process anyways. The ninja executable (like the fortran compiler) does need to be installed and on your $PATH, but it doesn't need to be pip-installed.

[^1]: The transition to this process, though, has been pretty traumatic. Packages weren't previously built in isolated environments, and it turns out that a lot of existing packages, including py3nj before #23, fail when built like this. I definitely think this transition will be a good thing in the long run, but right now it's still pretty painful.

I changed the venv environment because I had to create a second one, after the first command's output got erased in the terminal (because it was too long). I also piped the streams to a file using python -m pip install --no-cache-dir -vvv py3nj > log2.txt 2>&1

Thanks for running those commands (and carefully reporting the actual commands you ran!). Unfortunately, it seemed to install successfully. I was hoping that it would fail, so I could compare to an unsuccessful log. As it is, that's pretty much the same log as I get when I install py3nj myself.

Do you think you could reproduce the initial failure, but using the extra verbose pip command I gave? If you can, let me know the exact commands used, and the paths to any pythons involved. Right now, it seems to me like maybe the failure only happens if you try to install py3nj with the system python; not with a conda environment or a virtual environment? If that's the case, then (i) maybe the issue is ultimately some sort of permission error and (ii) I feel obliged to say that installing packages into the system python is a bad idea; you can break your OS doing that. But maybe I'm totally off-base.
