アナコンダを再インストールしても駄目で、原始的ですが、自分でuを直接256×256のbmpファイルにして、aviファイルへ結合という手段で、動作自体は確認できました。

答えになってなくて恐縮ですが、同じくgray_scott.pyが動かず、他のプログラムも動かないといいますか、中が透けたウィンドウ枠が出るだけです。windows7です。どなたか解決された方はいらっしゃらないでしょうか?

Windowsで上記のエラーでしたらこのissueと同じ原因なのではないでしょうか。
vispy/vispy#1503

こちらでは pyqtのバージョン4を使用したらvispyが動いたという報告があります。

手順としては以下のようになるでしょうか(私の環境ではエラーが出ないので、動作未検証です

$ conda clean --all 
$ conda install "pyqt<5"
$ python gray_scott.py

# ImportError : No module named 'xxx' が出たら $ conda install xxx して潰していく

コメントありがとうございました。
自分のPyQtもVer.5でしたので可能性が大きいと思いますが、pyqt4はconda installではインストールできませんでした。
pyqt4はソースファイルしかネットにないので、ダウンロードしてコンパイルして、condaにつなげる
pyではなくてC言語で自作する
pyqt4でも動くようにしてみる?
というのの、一番楽そうな方法で試してみようと思います。
vispyのバージョンを変えてみるとかでも良いかも。

alifebook_libのソースも読んでみたのですが、vispyで使用するバックエンドを PyQt5 に明示的に指定しているので、PyQt4をインストールする場合はこちらも書き換える必要があると思います。
https://github.com/alifelab/alife_book_src/blob/master/alifebook_lib/__init__.py#L2

本書のコードがPyQt4でも正常に動くのか、というのは別の問題なのですが、異なるバックエンドを統一的なインターフェースで扱えるようにすることがvispyの目的なら、動いてくれるのではないかと期待しています。

@tomotomo47 PyQt4を使用するのとは別のアプローチです

@079hide さんが挙げているのと同じ状況、つまり

RuntimeError: Using xxxx with no OpenGL context. エラーが発生していて、かつ

$ python -c "import vispy; print(vispy.sys_info())" した際に GL version が表示されない場合( GL version: '' のように:以下が空の場合 )は、vispyが使用するOpenGLターゲットを変更してみるのが有効かもしれません。

方法

https://github.com/alifelab/alife_book_src/blob/master/alifebook_lib/__init__.py#L2

vispy.use('PyQt5') を以下のそれぞれに変更して実行してみてください。

vispy.use('PyQt5', 'es2')
vispy.use('PyQt5', 'gl+')
vispy.use('PyQt5', 'pyopengl2')

解説

alifebook_libでは vispy.use() 呼び出し時に第二引数を省略しているため、ターゲットがデフォルトの gl2 固定になっているところを、別のターゲットに変更してみる試みです。

お使いの環境で gl2 ターゲットが動作しないので問題が起きているのではないかという仮説です。
そうだとすれば es2 - Use the ES2 library (Angle/DirectX on Windows) とあるので、Windows環境では vispy.use('PyQt5', 'es2') と書き換えれば動くのではないかと思います。

ターゲット一覧と解説: https://github.com/vispy/vispy/blob/master/vispy/gloo/gl/__init__.py#L112-L118

いろいろ助言頂きありがとうございます。
本によると、PyQt5を前提にしていると書いてあるので、PyQt4出ないと動かないというのは違うのかもしれません。
また、es2、gl+、pyopeng12についてやってみましたが、それらが無いというエラーになり、事態は後退してしまいました。

そもそも、エラーメッセージも載せて無いなか、コメント頂きありがとうございました。あらためて、エラー出力を載せます。
その前に、python -c "import vispy; print(vispy.sys_info())"の結果は、

OpenGLのバージョン2未満では glCreateProgram を利用できないため上記のエラーが出ているかもしれません。
グラフィックカードのドライバを更新してみたらどうなるでしょうか。
