How to install dictwrapper

[xchhuang]

Hi @ndeutschmann ,

I got errors while installing dictwrapper pip install git+https://github.com/ndeutschmann/dictwrapperas the following:

Building wheel for ruamel.yaml (setup.py) ... error
ERROR: Command errored out with exit status 1:
...

I tried on macOS and Windows 10, they have the same errors. Do you have any idea how to fix it? Thanks in advance.

With which version of Python did you try it? The error which occurs for me with Python 3.8 is File "/tmp/pip-install-l9mum064/ruamel.yaml/setup.py", line 69, in _convert if isinstance(node, (Str, Bytes)): NameError: name 'Str' is not defined So it is a problem related to the ruamel package, which was once broken for the latest Python version (https://bugzilla.redhat.com/show_bug.cgi?id=1714177). dictwrapper is a project by @ndeutschmann, so I am not sure, but I would guess that its dependencies need to be updated. I recommend to open an issue regarding the installation of dictwrapper in the respective repository.

Hi @NGoetz ,

Thanks for your reply. I am using Python 3.7.9.

I just realized that the dictwrapper package is quite simple. One easy way is to import them manually without installation.

Hi @xchhuang thanks for reporting this. Indeed in the GPU box where we actually run Zunis, we are still using python 3.6 where ruamel.yaml version 0.15.0 still did work, but it fails on 3.7+. We were explicitly using this version due to the warning on the package's page that they will at some point drop the API inherited from pyyaml and that the new one being implemented from 0.15.x on is not guaranteed to be stable.

The documentation is not super clear, however it seems least the current version of ruamel (0.16.12) is still retro-compatible. I have not yet conducted extensive testing so this is not officially released, however you can already use the following:

pip install pip install git+https://github.com/ndeutschmann/dictwrapper@ruamel_0.16.12

Hi @ndeutschmann ,

It seems to work now, thank you!

Hi again

I implemented a few basic unit tests in dictwrappers to make sure that the yaml import API is working with version 0.16.2 and indeed it seems to be the case so we will stick with that for now.

As a result, we now have

• dictwrapper v1.3 released both on github and PyPI (pip install dictwrapper and pip install git+https://github.com/ndeutschmann/dictwrapper should work)
• the requirements*.txt and setup.py in the Zunis project have been updated to use this version
• the PyPI release candidate for Zunis is also updated (i.e. you can install using pip install zunis==0.2rc3)

@xchhuang Could you please check whichever of these suits you?

Hi @ndeutschmann ,

I am using anaconda 4, python3.7 and I checked that all 3 ways can work for me in macOS and Windows 10. Thanks.

Great, thanks for checking
