Usage

Run(.py) compute_parallel > draw_auto $\ge$ state_parallel_auto > interactive_states. Means: compute raw data > draw jump step, coactivity distribution, generate pattern vedio $\ge$ statisticize states > build an interactive GUI for check states distribution in 3D phase space.

The folder analysis, connection, and model_file are edited from the beta version of Distributed_and_dynamical_communication from Shencong-Ni

Setup

Anaconda Prompt:

conda create --prefix "X:\path\.venv" python=3.11.7
conda activate "X:\path\.venv"

VsCode:

In the vary folder:

python.exe -m pip install -r packages.txt
python.exe -m pip install -r requirements.txt

Windows:

Add the three folders to path:

1. Open system property > advanced > environment variable;
2. Find or establish "PYTHONPATH" in system variable;
3. Add "X:\path\analysis;X:\path\connection;X:\path\model_file" to value, multiple path separated by ";";

Install Microsoft C++ Build Tools:

1. Open Microsoft C++ Build Tools page(Microsoft C++ Build Tools)
2. Download and run installer(Visual Studio Installer), select following option (or just select Desktop development with C++):
   1. C++ Build Tools work load;
   2. (Windows 10 SDK and MSVC v142/v143).
3. Restart PC after installed above tools.

Install ffmpeg

interactive phase diagram:

1. requirements: ipywidgets
2. Jupyter support:
   • Run in Jupyter Notebook need enable widgets:

   jupyter nbextension enable --py widgetsnbextension
   

LaTeX install:

Remote coding

Update requirements.txt and packages.txt

pip freeze > requirements.txt
pip list --format=freeze > packages.txt

prox setting

The command to use:

git config --global http.proxy http://proxyuser:proxypwd@proxy.server.com:8080

• change proxyuser to your proxy user
• change proxypwd to your proxy password
• change proxy.server.com to the URL of your proxy server

For example:

git config --global http.proxy http://127.0.0.1:4780
git config --global https.proxy https://127.0.0.1:4780
# may be unnecessary
git config --global http.proxy socks5://127.0.0.1:4780

.gitconfig

Here's a successful .gitconfig:

# This is Git's per-user configuration file.
[user]
	name = your_name
	email = your_email@example.example
# Please adapt and uncomment the following lines:
#	name = unknown
#	email = work@DESKTOP-2U2AG9K.(none)
[http]
	proxy = http://127.0.0.1:4780
[https]
	proxy = https://127.0.0.1:4780

SSH from PC and iPad (Code app) setting

SSH in iPad need no extra setting, following the tutorial of Cpolar will be enough. If something wrong, try to run as administrator while operating OS in the server.

Between intranet Windows

Tutorial C:\User\.ssh\config in PC:

Host server_user
    HostName 10.181.252.21(Intranet IP of your server)
    User server_user

sshd_config in server

Not clear now, but following sshd_config works:

Port 22
ListenAddress 0.0.0.0
PasswordAuthentication yes
PermitRootLogin yes
Subsystem sftp sftp-server.exe

Match User work
    ChrootDirectory X:\your_path
    ForceCommand none
    PermitTTY yes
    X11Forwarding no
    AllowTcpForwarding no
    PermitTunnel no
    Subsystem sftp internal-sftp -u 0002

If server's sshd_config has been modified by your fellow, possibly cause folder empty, or even cannot connect. As I know, sshd_config is all you need about SSH.

NTFS authority

• User your_account should full control X:\your_path and its sub-content
• System account sshd need Read/Execute permission

Configuration

# Grant the your_account user full control privileges
icacls "X:\your_path" /grant "your_account:(OI)(CI)(F)" /T

# Grant the sshd service account read access permission
icacls "X:\your_path" /grant "NT SERVICE\sshd:(RX)"

Verify permissions

icacls "X:\your_path"

Output should contain:

your_account:(OI)(CI)(F)
NT SERVICE\sshd:(RX)

If something wrong, try rigth-click your path in folder > property > Security, manually add accounts and permissions.

Check Chroot menu structure

Chroot specially require:

• X:\your_path has to be a genuine directory (non-symlink/mount point)
• The permissions of the directory and all its parent directories (up to the root directory)
  • Administrators and SYSTEM must have full control
  • Other users need at least the permission to traverse

Repair command

# set permission of parent directories
icacls "F:\" /grant "your_account:(RX)"
icacls "F:\" /grant "Administrators:(OI)(CI)(F)"
icacls "F:\" /grant "SYSTEM:(OI)(CI)(F)"

If something wrong, try rigth-click your path in folder > property > Security, manually add accounts and permissions.
