[Bug]: logo64.png: No such file or directory

[lenianiva]

Current Behavior

I created a python kernel using the instructions here, and it gave this error:

error (ignored): error: end of string reached
error:
       … while calling the 'getAttr' builtin

         at /builtin/derivation.nix:19:19: (source not available)

       … while calling the 'derivationStrict' builtin

         at /builtin/derivation.nix:9:12: (source not available)

       (stack trace truncated; use '--show-trace' to show the full trace)

       error: getting status of '/nix/store/g1xm5mkbhv8r135zsr8zdmarmffmrzby-source/logo64.png': No such file or directory

Expected Behavior

Jupyter would start running

Steps To Reproduce

1. Create the following files: flake.nix from nix flake init --template github:tweag/jupyenv. Modify kernels.nix:

{pkgs, ...}: {
  kernel.python.minimal = {
    enable = true;
    projectDir = ./.;
  };
}

2. pyproject.toml from https://github.com/tweag/jupyenv/blob/main/docs/documentation/how-to.md

[tool.poetry]
name = "jupyter-nix-kernel-ipython"
version = "0.1.0"
description = ""
authors = []

[tool.poetry.dependencies]
python = "^3.9"
numpy = "^1.23.0"
ipykernel = "^6.15.0"

[tool.poetry.dev-dependencies]
# build systems for dependencies
hatchling = "^1.3.1"

[build-system]
requires = ["poetry-core>=1.0.0"]
build-backend = "poetry.core.masonry.api"

3. Execute poetry lock
4. nix run

The previous version does not have the issue with logo64.png, but it still has issue with flit_core

Additional Context

touch logo64.png creates a different problem:

The solution about flit_core can be found here: https://github.com/tweag/jupyenv/blob/97f76f92fa14814e955a4f6847eaa4198525a19e/docs/documentation/how-to.md?plain=1#L169

The solution about flit_core can be found here:

if you don't know how to solve that issue via overrides.nix with poetry2nix. Please try my PR branch to get the native nixpkgs support for the kernels.

Thanks @GTrunSec,

I ran into the same issue and tried using your branch, e.g.

inputs.jupyenv.url = "github:GTrunSec/jupyterWith/chore";

Unfortunately this results in another error on nix run:

trace: warning: Unknown rpds-py version: '0.10.6'. Please update getCargoHash.
error: getting status of '/nix/store/g7lkqdx4wdz77p5lbsbx038956jhg813-source/logo-64x64.png': No such file or directory

The warning I attribute to https://discourse.nixos.org/t/poetry2nix-mismatch-cryptography-sha256-but-unable-to-modify/33897

The error happens as nix is looking for the logo in the kernel's projectDir. As a workaround I copied the logo over, which then makes nix run still error, but most likely due to an issue in poetry2nix as outlined in the above Discourse:

trace: warning: Unknown rpds-py version: '0.10.6'. Please update getCargoHash.
error: hash mismatch in fixed-output derivation '/nix/store/hcl9xsg13zccln3q1cknclvbvl4ckdry-rpds-py-0.10.6-vendor.tar.gz.drv':
         specified: sha256-AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA=
            got:    sha256-8bXCTrZErdE7JhuoudU/4dDndCMwvjy2a+2IY0DWDzg=

I saw there is a new mkPoetryKernel function. Should this be used in the future instead for a Poetry-based Python kernel?

@trevex for the logo error is a bug for sure(will be fixed tomorrow) second, if you don't know how to override the package with poetry2nix like https://github.com/GTrunSec/dataflow2nix/blob/main/nix/prefect/packages/overrides.nix#L23 just use the native python env: https://github.com/tweag/jupyenv/pull/524/commits/a56c43dbb0ccd18dd0f984eef890af745d62ea11#diff-459c8fd464b8b23e4b2f8ebb00690d572772b9a755aa7a5cce5d4574079edfa1R4
