F2PY first step

Environment setup for F2PY – first step, though no real project has been done yet.
Windows 7, 64bit

Referring to http://www.hedilict.com/f2py%E7%9A%84%E9%85%8D%E5%88%B6%E4%B8%8E%E4%BD%BF%E7%94%A8-windows-and-linux-platform/ (with acknowledgement)

1. Download Python 2.7 and install
https://www.python.org/downloads/release/python-2715/
(Description: for AMD64/EM64T/x64)

2. Write into system environment variable
Path = XPathX\Python27;XPathX\Python27\Scripts
where XPathX is substituted by the real path of Python

3. Download Numpy
https://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy
(numpy‑1.14.6+mkl‑cp27‑cp27m‑win_amd64.whl)
It is a .whl file, run cmd
pip install numpy_xxx.whl
I did not have problem here, but if there is “Fatal error in launcher: Unable to create process using ‘”‘ ” Try
python -m pip install numpy_xxx.whl

Now you can test the numpy is successful or not using:
python XPathX\Python27\Scripts\f2py.py

4. Download MinGW-64 as Fortran compiler and install
https://sourceforge.net/projects/mingw-w64/
select x64 and keep others unchanged

5. Add C:\mingw\mingw\bin into Path environment variable
I also added C_INCLUDE_PATH = C:\mingw\mingw64\include, though not sure this is really necessary.

6. Write a fortran file Hello.f and run
python XPathX\Python27\Scripts\f2py.py -c –fcompiler=gnu95 –compiler=mingw32 -m hello hello.f

I got an error message saying “error: Unable to find vcvarsall.bat” because I installed Visual studio 2010 where VS2008 is expected.
Refer to http://f.dataguru.cn/thread-160932-1-1.html
adopting Option 2:
open python path\Lib\distutils\msvc9compiler.py
change toolskey = “VS%0.f0COMNTOOLS” % version to toolskey = ”VS100COMNTOOLS”

It should be ok now, if everything is fine and you get hello.pyd.
run python
import hello
hello.hello()
Bingo!!

TeamViewer replaced Remote Desktop

RD has been used for a few years but just changed to TeamViewer, which performs much better than RD:
1. RD shows distorted model for ABAQUS;
2. RD aborts with error using Python to process figure/capture screens;
3. RD can not run some program remotely (probably still screen problem).
TV seems all good without any of these problems.

Copy and Paste is not working on my Remote Desktop Connection… what’s wrong?

From https://techtalk.gfi.com/copy-paste-working-remote-desktop-connection-whats-wrong/

Luckily fixing the issue is pretty straightforward and involves a few simple steps.

Load up task manager (right click taskbar and select Task Manager)
Go to the Processes Tab
Select rdpclip.exe
Click End Process
Go to the Application Tab
Click New Process
Type rdpclip
Click Ok

ABAQUS display windows disappeared

Strangely ABAQUS display windows disappeared.
The reason was just become drag to another screen with different resolution, where the python script windows was enlarged for coding. When drag back or restart on the main screen. All display windows disappeared.
Waste quite a bit time finding method to restore.
Just pull back to that screen and adjust the python code window size.
