            Answered 2021-Oct-15 at 21:11

            Found the problem.
            I was installing pandas_profiling, and this package updated pyyaml to version 6.0 which is not compatible with the current way Google Colab imports packages.
            So just reverting back to pyyaml version 5.4.1 solved the problem.

            For more information check versions of pyyaml here.

            Answered 2022-Feb-04 at 21:21

            I suspect this may have been an accident, though I prefer the new behavior.

            The new behavior is a consequence of a change to how the bytecode for * arguments works. The change is in the changelog under Python 3.9.0 alpha 3:

            bpo-39320: Replace four complex bytecodes for building sequences with three simpler ones.

            The following four bytecodes have been removed:

            • BUILD_LIST_UNPACK
            • BUILD_TUPLE_UNPACK
            • BUILD_SET_UNPACK

            The following three bytecodes have been added:

            • LIST_TO_TUPLE
            • LIST_EXTEND
            • SET_UPDATE

            On Python 3.8, the bytecode for f(*a, a.pop()) looks like this:

            Use of std::move in std::accumulate
            Asked 2022-Jan-04 at 12:31

            In my Fedora 34 environment (g++), std::accumulate is defined as:



            Answered 2022-Jan-01 at 20:50

            The value category of init + *first doesn't matter.

            init in init + *first is a lvalue.

            So if init + *first calls an operator+ overload taking the parameter by-value, it will cause a copy construction of that parameter

            But the value of init is not required anymore after init + *first, so it makes sense to move it into the parameter instead.

            Similarly a operator+ overload taking its first argument by rvalue-reference might be used to allow modification of the argument by the operation.

            This is what std::move achieves here.

            The standard specifies this behavior since C++20.



            How can I reuse a GitHub Actions workflow from the branch I'm currently working on?
            Asked 2022-Jan-03 at 21:12

            I'd like to abstract some of my GitHub Actions with a reusable workflow.

            In order to do this, I need to call my newly defined callable workflow in the format {owner}/{repo}/{path}/{filename}@{ref}

            e.g. (from the docs)



            Answered 2021-Oct-20 at 23:55

            It's as you said: It can't be done at the moment as Github Actions doesn't support expressions with uses attributes.

            There is no workaround (yet?) because the workflow interpreter (that also checks the workflow syntax when you push the workflow to the repository) can't get the value from the expression at that moment.

            It could maybe work if the workflow was recognized by the interpreter, but it doesn't event appear on the Actions tab as it's considered invalid.

            For the moment, you can only use tag, branch ref or commit hash after the @ symbol, the same way you use any action.

            Note that someone else had the same issue here
