To switch python2 under Linux Fedora 32

How to change default Python version on Linux/Fedora 28

under Fedora32

# alternatives --install /usr/bin/python python /usr/bin/python3.7 2
# alternatives --install /usr/bin/python python /usr/bin/python2.7 1

sudo alternatives --config python

2 プログラムがあり 'python' を提供します。

選択コマンド
-----------------------------------------------
* 1 /usr/bin/python3.7
+ 2 /usr/bin/python2.7

Enter を押して現在の選択 [+] を保持するか、選択番号を入力します:1

$ alternatives --list | grep -i python
python manual /usr/bin/python3.7

------------------------------------------------------

setup.pyを用いてインストールしたモジュールのアンインストール方法

python setup.py install --record install.txt

sudo cat inst.txt | sudo xargs rm -rf
------------------------------------------------------

to burn ISO image example:

samp：出力例
$ mkisofs -r -J -V "airCD" -o air_image.iso /run/media/mac/A12C-3EDA/

------------------------------------------------------

to edit gnome boxes example:

$ cd .config
$ cd libvirt/qemu/
samp：出力例
$ virsh edit centos6.8
-----------------------------------------------------

glibc version check

$ /lib/x86_64-linux-gnu/libc.so.6
or
# rpm -q glibc
# yum list installed | grep glibc

Thank You.

Sitex Air Renderer and Python cgkit

11年前の記事Happy Buddha!

python2.7でcgkitを扱う。sitex airでレンダリング。Happy Buddha

cgkitの良いところは、RIBで出力した設定を挿入して、レンダラーに合わせて設定できるところ。Airspace(windows only)を使って、shaderやlightの設定を、レンダリングして、スクリプトを参考にcgkitに挿入した。

以下、スクリプトbuddha_air.py
ありがとうございます。

Manjaro Linux18 python cgkit install

Manjaro Linux 18 (Arch linux) in Thunderbolt3 SSD

ノートPC,LG gram 13Z980-NA77JにThunderbolt3 SSD archgon X70 240GBを外付けで使って認識しました。Windows10高速スタートアップを切り、shiftキーを押しながら「再起動」から「デバイスの選択」、「Nvme0」選択して、再起動するManjaro Linuxが起動しています。
$ sudo hdparm -t /dev/nvme0n1
/dev/nvme0n1:
HDIO_DRIVE_CMD(identify) failed: Inappropriate ioctl for device
Timing buffered disk reads: 2184 MB in 3.00 seconds = 727.63 MB/sec

■ハードウェア確認。
$ sudo pacman -S bolt
$ sudo pacman -S hardinfo
$ sudo pacman -S lshw
$ sudo pacman -S gsmartcontrol
$ sudo lshw -class disk -class storage
$ sudo fdisk -l

$ sudo hdparm -t /dev/nvme0n1
$ sudo smartctl -a /dev/nvme0n1

$ sudo pacman -Syu

■日本語入力
$ sudo pacman -S --needed qt5-translations
$ sudo pacman -S fcitx-mozc fcitx-gtk2 fcitx-gtk3 fcitx-qt5 kcm-fcitx

$ nano .xprofile
以下を記入保存。
export GTK_IM_MODULE=fcitx
export QT_IM_MODULE=fcitx
export XMODIFIERS=@im=fcitx

■python cgkit installの準備。
$ sudo pacman -S python2-pygame python2-opengl python2-pyserial ode tk
$ sudo pacman -S boost boost-libs scons

AURに登録されているパッケージをインストールするためのパッケージを導入します。yay(Yet another Yogurt)をインストールします。

$ sudo pacman -S git
$ git clone https://aur.archlinux.org/yay.git
$ cd yay
$ makepkg -si

$ yay -S python2-pyode

■PIL1.1.7インストール
Manjaro Linuxはpython3が基本なので、ユーザのhomeにダミーディレクトリを作成します。
$ mkdir ~/bin
$ ln -s /usr/bin/python2 ~/bin/python
$ ln -s /usr/bin/python2-config ~/bin/python-config
$ export PATH=~/bin:$PATH
これでpython2.7が起動します。

毎回、python2を使うためには、
開いたターミナルで$ export PATH=~/bin:$PATHをします。

PIL1.1.7をダウンロード。
http://www.pythonware.com/products/pil/

$ cd Downloads/
$ tar xvf Imaging-1.1.7.tar.gz

$ python setup.py build_ext -i
$ sudo python setup.py install

■PyProtocolsインストール
http://peak.telecommunity.com/PyProtocols.html
http://peak.telecommunity.com/dist/

$ unzip PyProtocols-0.9.3.zip
$ sudo python setup.py --without-speedups install

■python cgkit2.0インストール
cgkitを入手します。
https://sourceforge.net/projects/cgkit/files/cgkit/
以下はcgkitのインストールです。
$ cd ../
~/Downloads$ tar xvf cgkit-2.0.0-py2k.tar.gz

環境を確認します。
$ cd cgkit-2.0.0/
$ cd utilities/
$ python checkenv.py
以下を実行します。
$ cd ../
$ cd supportlib/
$ scons
しばらく待ちます。
scons: done building targets.

$ cd ../
$ python setup.py build
■Build時のエラー対処
[solved]
py_slot.h,43行目snameの両側に空白スペースを入れる "_" sname "

[solved]
py_geoms1.cpp,line:145行 and line:166行 boost::python::make_tuple に変更します。

$ sudo python setup.py install

cgkitサイトのtutorialからdemoファイルを入手します。

python cgkit has been installed on my Zorin-OS-12.4-Core-64

Virtualboxにubuntu系のZorinOSをインストールしました。
はじめにRenderMan互換rendererのpixieをインストールしました。詳しくは前の記事に書きました。
http://rman.sakura.ne.jp/sb/log/eid528.html

以下をインストールします。
$ sudo apt install python-dev
$ sudo apt install python-opengl
$ sudo apt install python-pygame
$ sudo apt install libboost-python-dev
$ sudo apt install python-pyode
$ sudo apt install libode-dev
$ sudo apt install python-serial
$ sudo apt install python-protocols
$ sudo apt install scons

ubuntuのpackageのpython-pilはインストールしません。
64bitの環境でcgkitでのテクスチャがうまく使えないので
PIL1.1.7をダウンロードしてきます。
http://www.pythonware.com/products/pil/

以下、pil1.1.7をubuntu系でインストールするための設定です。
$ sudo ln -s /usr/lib/x86_64-linux-gnu/libz.so /usr/lib
$ sudo ln -s /usr/lib/x86_64-linux-gnu/libfreetype.so /usr/lib
$ sudo ln -s /usr/lib/x86_64-linux-gnu/libjpeg.so /usr/lib

$ sudo apt install python-tk tk8.5-dev tcl8.5-dev tk8.5 tcl8.5
ここでtkinterが動くか確認します。大文字のTになっています。
$ python -m Tkinter

pil1.1.7を解凍します。
$ cd Downloads/
$ tar xvf Imaging-1.1.7.tar.gz
$ cd Imaging-1.1.7/

setup.pyの以下の部分にpathを書き加えます。
$ nano setup.py

TCL_ROOT = "/usr/include/tcl8.5/"
JPEG_ROOT = "/usr/lib/x86_64-linux-gnu/"
ZLIB_ROOT = "/usr/lib/x86_64-linux-gnu/"
TIFF_ROOT = None
FREETYPE_ROOT = "/usr/lib/x86_64-linux-gnu/"
LCMS_ROOT = None

pil1.1.7をビルドします。

python setup.py build_ext -i

pil1.1.7をインストールします。ログを記録します。
sudo python setup.py install --record files.txt

アンインストールするときは以下を使います。
cat files.txt | xargs rm -rf

Bodhi Linux and Pixie Renderer install under gnome boxes

Ubuntu系のLinux 64bitでPixie Rendererを動かしました。
RIBが使える唯一のRenderMan互換rendererになるかもしれません。

Fedora28のgnome boxesにBodhi Linux5.0 64bitをインストールしました。
ダウンロードしたのは、bodhi-5.0.0-apppack-64.iso (1.5GB)
Pixie Rendererをビルドしました。
Pixie Rendererをダウンロードしてきます。
https://sourceforge.net/projects/pixie/

解凍します。
$ tar xvf Pixie-src-2.2.6.tgz
$ cd Pixie/
$ ./configure
...

    // Note that we actually created two patterns, and we merged them

    // together with a "blend".

    // The first pattern is a linear gradient that will span the V

    // direction of the parametric surface we will attach it to.

    // In this case we will use it on a sphere, where the V direction is

    // the one which connects the north and south poles (that is to say a

    // line of constant U and varying V is a meridian).

    // This gradient associates a color to each parallel of the sphere,

    // going from bright blue near the horizon to dark blue near the

    // azimuth.

    // The second pattern is again a "multifractal", which we use to model

    // very distant clouds. Note that we stretch it with a scaling, so that 

    // the clouds will look wide and thin.

    // The "blend" pattern finally blends the two. It uses the pattern

    // specified with "pattern" to mix more patterns. In particular it

    // defines a pattern-gradient that smoothly interpolates between

    // different patterns. In this case we use the linear pattern both to

    // model the distribution of the gradient and to model the gradient

    // itself.

    // The numeric value of the linear pattern has not been specified

    // (with a value-gradient), and so it goes from 0 to 1, as default.

    // Thus the "blend" will make a transition that goes from a clear

    // and bright sky near the horizon (at the V value of 0.3) to a cloudy

    // sky near the azimuth (at the V value of 1.0).
