****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.

10:31 Well, whatever you do, whether you eat or drink, do it all for God's glory.
Enjoy NumPy on PeterJohnNumPyV4.

Quoi de neuf dans la dernière version ?
the "PyRun_StringFlags() returns Nil but PyErr_Print() outputs Empty" Problem Solved and a 'Caffe' model Tutorial Removed Version;
we Changed Two Things at this time.
****1) we Solved the "PyRun_StringFlags() returns Nil but PyErr_Print() outputs Empty" Problem;
When you go to RunScriptView for the first time after you installed this App,
you needed to once go back to EditScriptView and then needed to go to RunScriptView again.
It was Due to that Py_FinalizeEx() wasNot called before Py_Initialize() was called.
and it was Hard to solve this problem
'cause the error message "fopen failed for data file: errno = 2 (No such file or directory), Errors found! Invalidating cache..." has Hidden this problem for many years.
As a result, the error message "fopen failed for data file: errno = 2 (No such file or directory), Errors found! Invalidating cache..." didNot relate to the problem that PyRun_StringFlags() returns Nil
for the first time when you installed this App.
****2) we Removed the tutorial
2.1) TutorialSeason003/s003DeepLearningColorizes.py
since it seems Richard Zhang's Image Colorization 'Caffe' model is No Longer provided.
Instead of it, Please use
"TutorialSeason008/s002PyTorchMpsDeepColorization.py"
on "PeterJohnPyTorch"
So that you Can use
Richard Zhang's Image Colorization 'PyTorch' model on 'PeterJohnPyTorch'.
