Cannot build xeus-python-demo

connorferster commented 3 weeks ago

Description

I am trying to build the xeus-python-demo locally but I am getting this strange error (extracted from much larger traceback, included below).

conda.auxlib.exceptions.ValidationError: 'emscripten' is not a valid Platform

I tried building it last night with the same result. And, after I hit this error, whenever I ran other commands in conda, e.g. conda create -n myenvname python=3.12, the commands would not run and I would get the same error! (Weird, yeah?)

Because it seemed like my miniconda3 installation was now broken, I completely removed conda (and all of my many environments), and re-installed conda anew from miniforge3 (which I had been meaning to do that anyway).

I just tried cloning the repo again fresh and installing it locally into a fresh conda environment. As before, the kernel did not install after running jupyter lite build. So I executed conda install xeus-python to install the xeus kernel into my conda environment. When I then ran jupyter lite build again, a completely different series of screens flashed by and then I got the same error as shown above (full stack trace below).

Get this! Now, again, my conda installation seems to be broken because I can no longer run conda create -n myenvname python=3.12 without it ending in the same error.

The conda-breaking part of this is probably an upstream issue as well but I could really use some guidance on what is happening here. How can I fix this? Are there any build steps I am missing?

Reproduce

Install latest miniforge3 on ubuntu
conda create -n jupyterlite python=3.12
conda activate jupyterlite
git clone https://github.com/jupyterlite/xeus-python-demo.git
cd xeus-python-demo
conda install jupyterlite-core
jupyter lite build -> Successfully builds Jupyterlite but without kernels
conda install xeus-python
jupyter lite build

CRASH

(See traceback below)

Expected behavior

Jupyterlite builds with xeus-python kernel and I am enjoying an excellent piece of new technology running in my browser! (Wow)

An unexpected error has occurred. Conda has prepared the above report.
If you suspect this error is being caused by a malfunctioning plugin,
consider using the --no-plugins option to turn off plugins.

Example: conda --no-plugins install 

Alternatively, you can set the CONDA_NO_PLUGINS environment variable on
the command line to run the command without plugins enabled.

Example: CONDA_NO_PLUGINS=true conda install

martinRenou commented 3 weeks ago

See https://github.com/jupyterlite/xeus/issues/100

connorferster commented 3 weeks ago

Thanks @martinRenou

I tried adding micromamba to the "build-environment.yml" file as such:

name: build-env
channels:
  - conda-forge
dependencies:
  - python
  - micromamba
  - pip
  - jupyter_server
  - jupyterlite-core >=0.3.0,<0.4.0
  - jupyterlite-xeus>=0.1.2,<0.2

But still no change. Did I interpret https://github.com/jupyterlite/xeus/issues/100 correctly?

martinRenou commented 3 weeks ago

ah you also need to use jupyterlite-xeus==0.2.0a0

connorferster commented 3 weeks ago

Thanks again @martinRenou. I am still running into the same problem :(

Here is the exact procedure followed for my most recent attempt:

Install new miniforge3
conda create -n jupyterlite python=3.12 jupyterlite-core
conda activate jupyterlite
pip install "jupyterlite-xeus==0.2.0a"
jupyter lite build --XeusAddon.environment_file=environment.yml

Here are the contents of my build-environment.yml:

name: build-env
channels:
  - conda-forge
dependencies:
  - python
  - micromamba
  - pip
  - jupyter_server
  - jupyterlite-core >=0.3.0,<0.4.0
  - jupyterlite-xeus==0.2.0a0

And here are the contents of my environment.yml:

name: xeus-lite-wasm
channels:
  - https://repo.mamba.pm/emscripten-forge
  - conda-forge
dependencies:
  - xeus-python
  - numpy

Is anything jumping out at you as blatantly incorrect? Thank you for any time you are able to spend reviewing this. Much appreciated.

An unexpected error has occurred. Conda has prepared the above report.
If you suspect this error is being caused by a malfunctioning plugin,
consider using the --no-plugins option to turn off plugins.

Example: conda --no-plugins install 

Alternatively, you can set the CONDA_NO_PLUGINS environment variable on
the command line to run the command without plugins enabled.

Example: CONDA_NO_PLUGINS=true conda install

  - jupyterlite-xeus==0.2.0a0

Not sure the jupyterlite-xeus pre-release is available on conda-forge. So maybe worth trying with pip for now:

  - pip:
    - jupyterlite-xeus==0.2.0a0

jtpio commented 3 weeks ago

FYI @connorferster this seems to be doing the trick: https://github.com/jupyterlite/xeus-python-demo/pull/40

Even with micromamba not listed in the build-environment.yml file, but it's likely because it's already installed as part of the workflow here:

https://github.com/jupyterlite/xeus-python-demo/blob/402a4955eb9d259417dffb82fdeb02225519de78/.github/workflows/deploy.yml#L24

connorferster commented 3 weeks ago

Thank you @jtpio and @martinRenou, I really appreciate your assistance.

The issue is conda. Even though I am including micromamba in my "build-environment.yml" it is still not working.

Solution:

Completely uninstall conda
Install micromamba (as a conda replacement)
Go about business as usual using micromamba only

When I completely omit conda from the process then everything goes smoothly (as advertised). However, because I would prefer to use conda in my local environment, it seems I will have run the build process on a separate server (GitHub Actions, or otherwise) as you have demonstrated.

I have raised this issue on the conda repo but have heard nothing back. So, if anyone is encountering this same issue and reading this, then you will need to create a computing environment where conda is completely absent in order to make the build work.

connorferster commented 3 weeks ago

Also, I just want to say:

Jupyterlite, especially with the xeus kernel, is a game-changer for folks who cannot install Python on their work computers for various reasons. Thank you all so much for this incredible effort. I will be deploying a Jupyterlite site for people in my industry and I expect it to be popular. Thank you thank you thank you!

jtpio commented 3 weeks ago

Thanks @connorferster!

I have raised this issue on the conda repo but have heard nothing back

Which issue is it? There is also https://github.com/conda/conda/pull/13962 which would likely fix this.
