Utilizo el método pip para instalar en Google Lab. Pero no estoy seguro de por qué no funciona. Esto es lo que tengo código

pip install "dask[dataframe]" --upgrade

Si tomo el marco de datos para usarlo. Notificación como esta sucede código

 import dask.dataframe as dd

Estoy usando Google Colab para escribir, ¿por qué no está disponible aquí? ¿Cómo podría solucionarlo?

Si ejecuto !pip install "dask[dataframe]" en un cuaderno de Colab y luego importo dask.dataframe como dd, no obtengo ningún error.

@AlexK Sigo teniendo el mismo problema. ¿Esto es algo causado por colab?

Quizás hubo este problema de Github con una solución recomendada que podría ayudarte: github.com/dask/dask/issues/6301

@AlexK, gracias, pero ya lo intenté. Tampoco funciona. Lo resolví copiando cada código en un nuevo archivo colab. Funciona. Pero no estoy seguro de que la próxima vez que abra esto funcione o no

Prueba esto.

!python -m pip install "dask[complete]"
import dask
import dask.dataframe as dd

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

Necesito rInicie el tiempo de ejecución después de la instalación antes de importar.
