QUESTION
I'd like to migrate away from --define flags and to build settings per: https://docs.bazel.build/versions/5.0.0/skylark/config.html
Here's the rule to which I'd like to pass command line values.
- Can this be done in practice when using loaded rules?
- Can one access build setting values in rule fields of .bazel files, or are they only accessible to Starlark configurations?
- Is there a way to effectively "subclass" a loaded rule without having access to a published implementation? If
_implwere public, it seems like I might be able to wrap it with my own implementation that passes it the flags.
I'm somewhat new to Bazel and still figuring out the right way to conceptualize this stuff. Any guidance is appreciated!
Current Approachbackend/BUILD.bazel:

Answered 2022-Feb-01 at 22:10rules_docker has attrs like repository_file and tag_file for exactly this kind of thing. You can generate those files however you want, including a custom rule that uses your user-defined flags. I'd do it like this:
QUESTION
Been reading the Bazel docs over and over to the point where nothing feels new, but I cannot seem to grasp how to setup configurations and variants for variants other than the native ones, e.g. --cpu and --compilation_mode.
To explain what I mean with configuration and variants, consider this table of Configuration rows, and Variant Points columns, and Variant cells (making this table up, hope it at least makes abstract sense):
Has hardware module X Connected on interface Fail fast Customer configuration 1 Yes Ethernet Yes Customer configuration 2 Yes USB Yes Customer configuration 3 No USB No Debug hw configuration No UART YesFrom a Bazel user perspective:
- All targets should be buildable for all configurations by default
- Not ok adding "Customer configuration X" everywhere on adding a configuration
- Configuration specific components should be possible to explicitly state which configuration it is specific to
- I think this is what constraint_value is for
- Rules should add flags based on configuration
- For example
-DVARIANT_POINT_CONNECTED_ETHfor Ethernet connection and-DVARIANT_POINT_CONNECTED_USBfor USB connection
- For example
- I want a simple build command for building/testing/running a single configuration
- Something like
bazel build //my/target --//:configuration=debughw - Think there is something about it in the skylark config docs, but not seeing how to go from the example to using constraint_values and
select()in rules
- Something like
ANSWER
Answered 2021-Oct-15 at 23:59You're looking for platforms. Build settings (that you found first) are better for independent pieces of configuration where setting them in any permutation is useful, vs platforms tie all the pieces together. The resulting settings and constraints can then be used to drive compiler flags and limit targets to certain configurations.
For your example, I think something like this makes sense:
QUESTION
I am trying to import all 9 columns of the popular MPG dataset from UCI from a URL. The problem is , instead of the string values showing, Carname (the ninth column) is populated by NaN.
What is going wrong and how can one fix this? The link to the repository shows that the original dataset has 9 columns, so this should work.
From the URL and we find that the data looks like
...ANSWER
Answered 2021-Sep-30 at 22:51It’s literally in your read_csv call: comment='\t'. The only tabs are before the Carname field, which means the way you read the fle explicitely ignores that column.
You can remove the comment parameter and use the more generic separator \s+ instead to split on any whitespace (one or more spaces, a tab, etc.):
QUESTION
I want to do LDA (linear discriminant analysis) with the Auto dataset of the ISLR package. To start off, I am trying to take the cars with year = 75 and use it as a "test set", where cars of all other years will be used as a "training set". However, it seems that I've made a mess of things. For instance, in my code below, sequentially using the replace function for the values of mpg.year75 just results in everything being set to high:

I am trying to use the rename() function of the dplyr package to change the variable mpg to mpgclass:
ANSWER
Answered 2021-Sep-23 at 07:08rename works for me, perhaps you have a function conflict with another package. Try using dplyr::rename.
To change the columns based on range of values you may use case_when or cut.
QUESTION
I want to get the time every rule costs when executing a bazel build. I found aspect in bazel,use that feature I can print each rule's finish time in log file.
However I found aspect of a rule executing after the rule executing, with that I can't get when a rule start executing.
So Is there any way to extend a rule before it executing?
...ANSWER
Answered 2021-Aug-09 at 18:22Bazel has builtin performance profiling which provides lots of details. Run your build with --profile=/tmp/profile.gz and then load the resulting file into chrome://tracing in any Chrome instance. You'll get something like this (from the docs):
Note that due to bazelbuild/bazel#12965 you may need to manually un-gzip it before loading into Chrome.
There's also documentation on the profile file format if you want to write a tool to analyze it yourself.
QUESTION
Firstly, apologies if the title of this question isn't clear - let me try to explain. I'm scraping some data from www.bbc.co.uk/iplayer. The site is structured in such as way that there are approx 10 categories (e.g. sports, drama, popular now), within which there are approximately 10 programmes. I've managed to scrape most of the data I need (programme title, genre, and synopsis) and I know how to combine this into a new data frame. Here's my code so far:
...ANSWER
Answered 2021-Jul-16 at 08:32You could use purrr::map_dfr to apply a function to each section node. That function would return a tibble, in this case, of the required info for each section. map_dfr would then map these tibbles to a final DataFrame. Within the tibble, the shorter header would be recycled to match length of the other columns.

I need help with heatmaps, I am first timer and I usually have problems when coming to frequencies graphs.
I need to create a heatmap with date on x axis, and crepus on y axis. That is fine.
The variable I want for the color is the frequency of all species (speciesname), which would be the total sum of all species of the variable nmb_individuals, obviously by date and crepus value.
When trying it, I get a completely blank heatmap, though the scale looks good:

Install skylark
You can use skylark 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.
