QUESTION
to build and run a local instance, im following the tutorial at
https://haha.readthedocs.io/en/latest/install.html
but i use the git repo

instead of
https://github.com/rtfd/readthedocs.org.git
for the "git clone" command, as the link in the tutorial does not exist.
i am also using venv

QUESTION
I want to install packages from poetry.lock
file; using poetry install
.
However, the majority of packages throw the exact same error, indicating a shared fundamental problem.
What is causing this? What is the standard fix?
Specification:
- Windows 10,
- Visual Studio Code,
- Python 3.8.10 & Poetry 1.1.11,
- Ubuntu Bash.
Terminal:
rm poetry.lock
poetry update
poetry install
ANSWER
Answered 2022-Mar-23 at 10:22This looks to be an active issue relating to poetry. See here - Issue #4085. Some suggest a workaround by downgrading poetry-core
down to 1.0.4.
There is an active PR to fix the issue.
QUESTION
Is it possible to set YAML line width, when dumping to file with ruyaml?
When dumping a YAML object to file with pyyaml and its content is fairly long 82+(or something similar) characters, there is a row break inserted. This can be circumvented by giving the parameter "width" to the dump function, where you can either give a specific length or as in the example below "inf".
That possibility seems to be missing in ruyaml.
...ANSWER
Answered 2022-Feb-21 at 14:33Stumbled upon the "width" member variable on the YAML instance, seems to have the same effect as sending width=X
to PyYaml dump function.

I have tried the similar problems' solutions on here but none seem to work. It seems that I get a memory error when installing tensorflow from requirements.txt. Does anyone know of a workaround? I believe that installing with --no-cache-dir would fix it but I can't figure out how to get EB to do that. Thank you.

is very memory hungry application.
QUESTION
I have a local python project called jive
that I would like to use in an another project. My current method of using jive
in other projects is to activate the conda env for the project, then move to my jive
directory and use python setup.py install
. This works fine, and when I use conda list
, I see everything installed in the env including jive
, with a note that jive
was installed using pip.
But what I really want is to do this with full conda. When I want to use jive
in another project, I want to just put jive
in that projects environment.yml
.
So I did the following:
- write a simple
meta.yaml
so I could use conda-build to buildjive
locally - build jive with
conda build .
- I looked at the tarball that was produced and it does indeed contain the
jive
source as expected - In my other project, add jive to the dependencies in
environment.yml
, and add 'local' to the list of channels. - create a conda env using that environment.yml.
When I activate the environment and use conda list
, it lists all the dependencies including jive
, as desired. But when I open python interpreter, I cannot import jive
, it says there is no such package. (If use python setup.py install
, I can import it.)
How can I fix the build/install so that this works?
Here is the meta.yaml, which lives in the jive
project top level directory:
ANSWER
Answered 2022-Feb-05 at 04:16The immediate error is that the build is generating a Python 3.10 version, but when testing Conda doesn't recognize any constraint on the Python version, and creates a Python 3.9 environment.
I think the main issue is that python >=3.5
is only a valid constraint when doing noarch
builds, which this is not. That is, once a package builds with a given Python version, the version must be constrained to exactly that version (up through minor). So, in this case, the package is built with Python 3.10, but it reports in its metadata that it is compatible with all versions of Python 3.5+, which simply isn't true because Conda Python packages install the modules into Python-version-specific site-packages
(e.g., lib/python-3.10/site-packages/jive
).
Typically, Python versions are controlled by either the --python
argument given to conda-build
or a matrix supplied by the conda_build_config.yaml
file (see documentation on "Build variants").
Try adjusting the meta.yaml
to something like
