Error with "import vertexai"

[tln888111]

Hi,

I'm trying to use GCP: Vertex Ai. I already installed the Vertex AI SDK for Python package successfully.

I can "from google.cloud import aiplatform" successfully. However, "import vertexai" caused error as follows: No module named 'vertexai'

I also already installed the module vertexai in the linux machine successfully.

Would you help to show me what caused the error? Thanks so much in advance.
