AnacondaにインストールされているモジュールをPythonプログラムから実行したい

Question

Vscodeでipynbファイルを以下のように作成しましたが、エラーとなってしまいました。

import subprocess

cmd_htseq = r"htseq-count -f bam C:\test\test.bam C:\test\test.gtf > C:\test\count_data.txt"
subprocess.run(cmd_htseq.split())

   1209                 # Child is launched. Close the parent's copy of those pipe

FileNotFoundError: [WinError 2] 指定されたファイルが見つかりません。

どうすれば、実行出来るでしょうか？
