QUESTION
Is the first time that I'm scraping a website. The problem is that are two different tables with the same classname. By far I have learned that to find the data I have to find it by the classname of the HTML tag. The code works to scrape the data from the first table, but I want to do it for the second table as well.
...ANSWER
Answered 2022-Mar-29 at 12:12I think you can get both tables using find_all and store them as 'bs4.element.ResultSet' (tables in below code) which can iterate through using the for loop or through their indices

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.lockpoetry updatepoetry 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
I have pretrained model for object detection (Google Colab + TensorFlow) inside Google Colab and I run it two-three times per week for new images I have and everything was fine for the last year till this week. Now when I try to run model I have this message:
...ANSWER
Answered 2022-Feb-07 at 09:19It happened the same to me last friday. I think it has something to do with Cuda instalation in Google Colab but I don't know exactly the reason
QUESTION
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.

Answered 2022-Feb-05 at 22:37The error says MemoryError. You must upgrade your ec2 instance to something with more memory. tensorflow 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.yamlso I could use conda-build to buildjivelocally - build jive with
conda build . - I looked at the tarball that was produced and it does indeed contain the
jivesource 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

ANSWER
Answered 2022-Jan-26 at 16:45The problem is that the R binary in rocker/r-ver:latest is compiled against a different BLAS library to the one which the numpy on PyPI is compiled against.
This was explained to me by Tomasz Kalinowski here.
The solution is to ensure numpy uses the same BLAS libraries as rocker/r-ver's R binary does. An easy way to ensure this is to compile numpy from source. This compilation could be performed at either image build-time or container runtime.
To compile numpy at container runtime we can leave our Dockerfile as is, and add a call to system2() after our initial call to reticulate::virtualenv_create(). Altering test.R to become:
QUESTION
I've looked at quite a few grammar parsers, but none of them seem to be able to generate all parsings of an ambiguous grammar. (I've also checked these questions, which don't provide any helpful solutions to my problem.)
How can I go about generating all the parsings of an ambiguous grammar?
For example, imagine my (ambiguous) grammar is
...ANSWER
Answered 2022-Jan-24 at 23:16Depending on how complicated your grammar is, you can probably just implement it yourself. Most libraries optimize to help with ambiguity, but if you want all the options, you can just do a simple recursion:

There is no longer any implicit import machinery
So if Google.py is in the same directory as the code you pasted, you have to reference it's realtive location explicitly.

Install pyparsing
You can use pyparsing like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
