python - PyMEL コアをインポートするにはどうすればよいですか?

Question

をインポートしmaya.standaloneて初期化し、pymel.core as pmcPowerShell で実行されている Maya Python インタープリターにインポートしています。この時点で、多くの警告が表示されます。呼び出した後: xform, shape = pmc.polysphere()、警告が表示されます:name 'xform' is not defined

これは pymel インポートからの出力です

私は本「Practical Maya Programming」に取り組んでいます。本からのテキストは次のとおりです。

それでは、Maya と PyMEL について掘り下げていきます。mayapy インタープリタで Maya を初期化することから始めて、標準の Python 機能以上のものを使用できるようにします。次のコードに示すように、maya.standalone.initialize を呼び出してこれを行います。

>>> import maya.standalone
>>> maya.standalone.initialize()
>>> import pymel.core as pmc
>>> xform, shape = pmc.polySphere()

pymel.core のインポートは暗黙のうちに maya.standalone.initialize を自動的に呼び出しますが、ここでは明示的に行うので、何が起こっているのかは明らかです。将来的には、通常は maya.standalone.initialize の呼び出しをスキップして、pymel.core だけをインポートできます。

基本的な Python を使用して、Maya ノードを表すこれらの PyMEL オブジェクトについて多くのことを発見できます。たとえば、いずれかのオブジェクトのタイプを確認するには、組み込みのタイプ関数を使用できます (この章の後半でタイプについてさらに深く掘り下げます)。

インタープリターで発生しているエラーを説明し、解決策を提供できる人はいますか?

Windows を使用しているため、Powershell ISE を使用していないことを確認してください。標準の Powershell を使用するだけです。

@Boon が言うように、これらのエラーのほとんどは、Maya のプラグインと、より適切に記述された可能性のある部分に起因します。

プログラミングの学習に集中しているため、これらのプラグインは必要ありません。インタラクティブな Maya セッションから無効にすることができます。

マヤを開きます。
Windows->Settings/Preferences->Plugin Manager を選択します
上部のセクションにないすべてのプラグイン (Xgen、Bifrost、Substance、mtoa など) の「Loaded」と「Auto Load」をオフにします。
マヤを閉じます。

シェルでもう一度試してください：

mayapy
import maya.standalone
maya.standalone.initialize()
import pymel.core as pm

この時点で、Y-Up に関する警告と Alembic のバージョン情報だけが表示されます。心配することは何もありません。

プロンプトは>>>、どちらが良いかです。これで pymel コマンドを入力できるはずです:

pm.about(version=True)
pm.polySphere() 
pm.ls(type="mesh")

編集

PowerShell を使用していてプロファイルを設定している場合は、次の行を profile.ps1 に追加することで時間を節約できます。

function ms { mayapy -i  -c "import maya.standalone;maya.standalone.initialize();import pymel.core as pm;print('maya standalone initialized and pymel.core imported as pm')" }

これで、PowerShell を開いて入力し、msコーディングを開始できます。

python - PyMEL コアをインポートするにはどうすればよいですか?
