    Hydrus in Anaconda

Running Hydrus from source (git) in the main Anaconda environment.
Install Chocolatey and Anaconda

Note: can also install anaconda manually, instead.
In an administrator powershell:
Set-ExecutionPolicy Bypass -Scope Process -Force; [System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072; iex ((New-Object System.Net.WebClient).DownloadString('https://community.chocolatey.org/install.ps1'))

Restart the shell, probably.
choco install anaconda

Install dependencies

In administrator anaconda powershell prompt:
conda install   cryptography python-dateutil beautifulsoup4 chardet lxml lz4 numpy psutil pyOpenSSL PySocks PyYAML Send2Trash service_identity Twisted requests   # likely already installed
conda install   html5lib   # okay dependencies available in conda
conda install   pyqt5-sip   # tricky, might be useless
pip install -U  cbor2 cloudscraper python-mpv   # just some stuff not in conda
pip install -U  opencv-python Pillow   # can also use opencv-python-headless   # heavy binary stuff
pip install -U  pyqt5   # ?+ pyqt5-qt5 ?+ qtpy   # break stuff
# To consider, instead of pyqt5:
#   pip install -U PySide6

Get mpv-2.dll, likely from mpv-dev-x86_64-v3-...:
mpvnet-player/mpv.net#469
and put it here.
Fix sqlite3 fts4

Check (before and after):
python -c "import sqlite3 as m; c = m.connect(':memory:'); res = c.execute('select 1'); print(res.fetchall()); res = c.execute('create virtual table tst1 using fts4()'); print(res)"`

Get the sqlite library (and CLI along the way):
choco install sqlite sqlite.shell

Replace the anaconda's sqlite dll:
cp c:\ProgramData\chocolatey\lib\SQLite\tools\sqlite3.dll  c:\tools\Anaconda3\Library\bin\sqlite3.dll

Run

Put in a hydrus_client.cmd script:
REM %windir%\System32\WindowsPowerShell\v1.0\powershell.exe -ExecutionPolicy ByPass -NoExit -Command "& 'C:\tools\Anaconda3\shell\condabin\conda-hook.ps1' ; conda activate 'C:\tools\Anaconda3' "
REM c:\tools\Anaconda3\Scripts\activate.bat C:\tools\Anaconda3
@CALL "c:\tools\Anaconda3\condabin\conda.bat" activate
cd c:\hydrus\hydrus\
C:\tools\Anaconda3\python.exe c:\hydrus\hydrus\client.py
pause

Packages debug

In a cygwin shell:
( /c/tools/Anaconda3/Scripts/conda.exe list; /c/tools/Anaconda3/Scripts/pip3.exe freeze; ) | grep -i qt
