Python3 导入错误：未定义符号：aes_hw_encrypt

Question

我正在尝试使用 DialogFlow 在 Raspberry Pi 4 上制作一个闲聊聊天机器人，但出现此错误：

ImportError: /usr/local/lib/python3.7/dist-packages/grpc/_cython/cygrpc.cpython-37m-arm-linux-gnueabihf.so: undefined symbol: aes_hw_encrypt

我的代码如下：

"""
Libraries used:

dialogflow        1.1.0 - I did pip3 install dialogflow -U and it upgraded to this
google-api-core   1.29.0
os   Latest version - not sure 

"""

import os
import dialogflow
from google.api_core.exceptions import InvalidArgument

os.environ["GOOGLE_APPLICATION_CREDENTIALS"] = 'secrets.json'

DIALOGFLOW_PROJECT_ID = '[test_id]'
DIALOGFLOW_LANGUAGE_CODE= '[en]'
SESSION_ID = 'me'

text_to_be_analyzed = "Howdy"

session_client = dialogflow.SessionsClient()
session = session_client.session_path(DIALOGFLOW_PROJECT_ID, SESSION_ID)
text_input = dialogflow.types.TextInput(text=text_to_be_analyzed, language_code=DIALOGFLOW_LANGUAGE_CODE)
query_input = dialogflow.types.QueryInput(text=text_input)
try:
    response = session_client.detect_intent(session=session, query_input=query_input)
except InvalidArgument:
    raise

print("Query text:", response.query_result.query_text)
print("Detected intent:", response.query_result.intent.display_name)
print("Detected intent confidence:", response.query_result.intent_detection_confidence)
print("Fulfillment text:", response.query_result.fulfillment_text)

pip3 list给了我：
