Recently I tested transonic with this simple code: transonic_test.py ```python import numpy as np from transonic import jit,boost #transonic def norming(float[]) @boost def norming(np_array): norm_array = np.linalg.norm(np_array, axis=1) return norm_array ``` I use this command to compile it ahead-of-time: ```bash transonic transonic_test.py -af "-march=native -DUSE_XSIMD -Ofast" ``` which ran successfully. However, when I execute the following program transonic_test_main.py ```python from transonic_test import * from timeit import default_timer as timer start_1 = timer() for i in range(1000): in_arr = np.random.rand(10000, 3) norm_arr = norming(in_arr) end_1 = timer() print("time spent are {}".format(end_1 - start_1)) ``` with python, the output shows: ``` DEBUG Using rich for tracking progress. WARNING Pythran file does not seem to be up-to-date: <module '__pythran__.transonic_test_4f3187f787722cc89a00775cc0002503' from '/Users/jw598/Desktop/high_entropy_ alloy/__pythran__/transonic_test_4f3187f787722cc89a00775cc0002503.cpython-37m-darwin.so'> func: norming time spent are 0.3765912619999999 ``` with the timing almost the same as pure python. This problem is identical to the one reported here:\ https://stackoverflow.com/questions/64857530/transonic-run-python-code-instead-of-pythran My system configuration is: OS: MacOS Catalina 10.15.7\ gcc: 10.2.0\ python: 3.7.7\ pythran: 0.9.8.post2\ transonic: 0.4.7.post0 Thanks a lot!
