Hi Guix users!
Today I tried to import another package from PyPI:
~~~~
$ guix import pypi 'jupyterlab@2.1.5' --recursive
following redirection to `https://pypi.org/pypi/jupyterlab@2.1.5/json/'...
Backtrace:

But when I leave away the version, it works:

So I checked in the manual and there is says:
> A specific package version may optionally be specified by following
the package name by an at-sign and a version number as in the following
example:
> guix import hackage mtl@2.1.3.1
But that is in the "hackage" import section. Is the same not available
for PyPI?
When I check with:
~~~~
$ guix import pypi 'jupyterlab@2.2.8' --recursive
following redirection to `https://pypi.org/pypi/jupyterlab@2.2.8/json/'...
Backtrace:

It also errors, although 2.2.8 is the version shown on PyPI currently.
Do the various importers work differently?

The file <https://pypi.org/pypi/jupyterlab@2.2.8/json/> does exist but the file <https://pypi.org/pypi/jupyterlab/json/> does and it contains the relevant information. The PyPI importer should be improved... or they changed their API. Thanks for the report. All the best, simon ^ permalink raw reply [flat|nested] 15+ messages in thread

Each importer could handle it properly (e.g., by turning it into "/") or return a friendlier ‘the foo importer does not yet support versions’ error.

(My guess: This functionality simply has not yet been implemented.) (Q2) Why are the manually imported packages not actually in files with their own name, but instead jinja2 -> python-xyt, tornado -> python-web, and pytest -> check? Why not (gnu packages python pytest) for example? (Q3) Is my process of finding the files in which the packages are correct or just working by chance? Basically I am creating temporary environments, in which I then lookup "where would the package be installed" and then exit the temporary environment to use that information in my imported package file's import expressions / use-modules expression. This seems to be a bit of a convoluted process, though worth it, if it always works in the end.

Unless it's needed to run the program and not just for the test suite, in which case it should go in propagated-inputs. There's no network available in the build environment so it can't retrieve ipykernel while building.

~~~~~END~~~~~ I have some thoughts about this: The Python error does not really tell me what is wrong. I don't know why the `WorkspacesAPITest` does not have an attribute named `lab_config`. One can see, that those are all API tests. Since there were problems in the previous step with network, perhaps it is a network thing here as well? (Is network, even if localhost for testing, available in the "check phase"?) It could also simply be, that some PyPI package has failing tests. I don't know how one could then skip such tests. I guess I will summarize everything in the end and put it in a repository as a kind of "guide", so that others can use it or learn from the process.

This means the next thing to fix would probably be to use another version of jupyterlab-server. 1.2.0 is a tag in the jupyterlab-server repository, which _seems_ to be the latest "stable" version, before a lot of alpha, beta, and release-candidate versions follow. I guess I could switch the commit in my `jupyterlab.scm` file to point to a different one? I can change the version to `2.0.0rc1`, but I do not know how the checksum is calculated. The checksum is shorter than what I see on simply PyPI: https://files.pythonhosted.org/packages/79/43/5249be5ee741a93f3fa60823caf9a276cadc3103dae16d6e36cc534fefd8/jupyterlab_server-2.0.0rc1.tar.gz#sha256=733b149c5ab8e50ea5f2897c323047257060e7bf2dc0fa88663181427bec605d and base32 should only make it longer, not shorter. Can you explain how to switch a version manually and calculate the checksum to match another version?

For a tarball like the one at pythonhosted you'd download the file and then run 'guix hash the-file'. If you're using a source code repository then from the top level of the repo you'd run 'guix hash --exclude-vcs --recursive .', or 'guix hash -rx .' for short. The hash layout that Guix uses is the sha256 of the tarball base32 encoded, but with a change in the letters used. For python packages you can specify a version number, so in this case it'd be 'guix import pypi jupyterlab_server/2.0.0rc1'. Some other importers us the '@' symbol to specify version number and I think some don't support using other versions at all. I don't know how compatible different major versions of jupyterlab-server are with each other, so I'd stick with 1.2.0 for now. > Regards, > Zelphir > > On 10/19/20 8:19 PM, Zelphir Kaltstahl wrote: > > > > Hello Efraim, > > > > Thanks for your patience!

This means however, that the check phase will fail, because of the failing tests in the jupyterlab_server repository on version 1.2.0. Unless there is a way to disable running those specific tests, I guess this means, that only getting the tests to pass in the jupyterlab_server repository will solve the problem? >> Regards, >> Zelphir >> >> On 10/19/20 8:19 PM, Zelphir Kaltstahl wrote: >>> Hello Efraim, >>> >>> Thanks for your patience!

Perhaps that will help the tests pass. The thing is, that I already tried to run the tests within the jupyterlab_server repository and they do not pass there either. They are simply failing currently / jupyterlab_server stable is not in a clean state. At first I had to figure out how to get a test environment set up, but I solved that one: https://github.com/jupyterlab/jupyterlab_server/pull/129. I think there is nothing on the Guix side to make them magically pass, when they even fail in the original repository / code. Where do you grep for add-installed-pythonpath in other packages? I have looked here https://git.savannah.gnu.org/cgit/guix.git/tree/guix/packages.scm, but that seems to be the package implementation of Guix itself, not the packages it offers. Ah, I think I found it: https://git.savannah.gnu.org/cgit/guix.git/tree/gnu/packages.

Assuming WorkspacesAPITest does actually have an attribute named lab_config then you'll want to add the installed package to the python path during the check phase. There are a number of packages which do this.
