how to find the index of the first value for each row of a matrix?

Running ubuntu 18:

'pip install py-find-1st' just stalls, nothing happens.

Hello, I am unfortunately not able to see what your problem could be. For me things seem to build fine under python 3.8 with pip21.1.3. I have precompiled anaconda packages available in the channel roebel here. The package for python 3.8 was indeed missing but I just compiled and uploaded it. So you should be able to use conda to install it into your environment like this

 conda install -c roebel py_find_1st 

Let me know if this helps.

Due to the numpy import in setup.py, installing this library as dependency is very difficult, since it requires to be a 2 step process at all times:

pip install numpy
pip install py_find_1st

Installing only pip install py_find_1st in new virtual environment results in an error.

I think this could be improved by wrapping the numpy-import into a try/except block, catching ImportError, then running a pip install numpy from the setup.py script and reimport numpy (this time it should not fail since numpy is now available).

I've seen this in some other project recently, but i can't currently refind that...

Does py_find_1st support detecting the NaN value?

arr = np.array([1, np.nan, 3])
utf1st.find_1st(arr, np.nan, utf1st.cmp_equal)

Expected behavior would give 1, while the code above outputs -1

libstdc++ was removed in macOS (XCode Command Line Tools v10), but py_find_1st is installable by changing to suggested libc++:

            if compiler_is_clang(self.compiler.compiler):
                for e in self.extensions:
                    e.extra_compile_args.append('-stdlib=libc++')
                    e.extra_compile_args.append('-Wno-unused-function')
                for e in self.extensions:
                    e.extra_link_args.append('-stdlib=libc++')

When trying to install py-find-1st on a MacBook with Apple's M1 processor, I get a massive error. I suspect its related to the new osx-arm64 architecture.

AssertionError: would build wheel with unsupported tag ('cp38', 'cp38', 'macosx_11_0_x86_64')

The error also says it failed to build Numpy, but Numpy is installed from the package on Conda-forge. (Numpy v1.19.4)

Any ideas on how to fix? Full error is attached, too big to post on Github.

Hello,
I am trying to install the project and I get the error "ERROR: Could not build wheels for py-find-1st which use PEP 517 and cannot be installed directly". I have a macOS and I am trying to install the project in a a conda environment with python 3.8.10. I tried pip install --no-build-isolation py_find_1st which I saw was the solution in a similar case, but unfortunately did not work for me. Could you please help me?

i have an error like that
python 3.8.6.
windows 10
How can i solve this error?

Hello, I've tried to install this extension for quite a bit of time, but I keep falling into the same issue when running the commands in the cmd.

I've asked a lot of people about how to fix it, but I didn't manage to find an answer anywhere.

I'm getting the same error message, whether I run python setup.py build_ext or python setup.py ìnstall in the cmd:

Would you have any idea on how to fix it and manage to install the extension?

I've no knowledge of C++, and noone managed to find a solution, I have visual studio 2017 installed as well as its build tools extension.
I've verified that I installed everything necessary, yet no way to make the installation work.

The extension looks like it has very nice performances, and I hope to be able to use it in the future, any help would be gladly appreciated.
