****PeterJohnNumPyV4 Now You Can Use NumPy 1.20.2 on CPython3.9.9. ****How To Use NumPy on PeterJohnNumPyV4;; Go To "TutorialSeason003/scripts/s007LSTMtrainingPlot.py". Then "Run Script". ****Not Yet implemented Features;; Basically, you Can Use all Functions of numpy.ndarray. **1; numpy.random;; please use Python3 Standard "random" module instead of it. 1.1); numpy.random.randn();; So we implemented pjRandN() function using NumPy and Python3 Standard "random" module. Documents/TutorialSeason003/scripts/pjLStermMemory.py;pjRandN() **2; numpy.linalg;; 2.1); numpy.linalg.norm();; So we implemented pjNorm() function using NumPy instead of it. Documents/TutorialSeason003/scripts/pjLStermMemory.py;pjNorm() 2.2); numpy.linalg.qr();; So we implemented pjQR() function using NumPy instead of it. Documents/TutorialSeason003/scripts/pjLStermMemory.py;pjQR(); **3; numpy.diag();; Basically, you Can Use all Functions of numpy.ndarray, so Please use numpy.ndarray.diagonal() instead of it. **4; numpy.fft; Not Yet implemented. **5; numpy.polynomial;; Not Yet implemented. **6; numpy.ctypeslib;; Not Yet implemented. ****When you Use this App withOut NumPy;; Using iPhone's "Files.app", Delete the NumPy's "__pycache__" folder below. Documents/PeterJohnNumPyV4/usrLocal/lib/python3.9/site-packages/numpy/__pycache__ If there doesNot Exist the NumPy's "__pycache__" folder, when you touched "Edit Script", this App Calls "Py_FinalizeEx()" So you Can Enjoy Scripting Comfortably. ****the WorkAround against the Well-Known Bug of NumPy and Python3.9;; NumPy and Python3.9 have a Well-Known Bug. While NumPy has been imported, "Py_FinalizeEx()" doesNot Release memory. So If you imported NumPy at the Second time, Python3 Crashes. so we made a WorkAround against the Well-Known Bug of NumPy and Python3.9. As the Specification of this App, If there Exists the NumPy's "__pycache__" folder, Documents/PeterJohnNumPyV4/usrLocal/lib/python3.9/site-packages/numpy/__pycache__ Even if you touched "Edit Script", this App doesNot call "Py_FinalizeEx()" This is Not a Perfect Solution But you Can Enjoy NumPy withOut Python3 Crashing. ****1st Corinthians 10:31, GNT; 10:31 Well, whatever you do, whether you eat or drink, do it all for God's glory. Enjoy NumPy on PeterJohnNumPyV4. Best Regards, --Yasushi Yassun Obata
