Issues with README instructions not working

[davetbo-amzn]

I'm running the instructions in README.md in a new python3.9 venv. I downloaded the dependencies and successfully ran the 3 pip install statements for boto3, botocore, and awscli. When I try to create the client as instructed with this code:

import boto3
print ('boto3 version:\n', boto3.__version__)
bedrock = boto3.client('bedrock', region_name='us-east-1')

I get this output and error (note I added the version print).

 amazon-bedrock-workshop]$ python3 test_client.py 
boto3 version:
 1.26.162
Traceback (most recent call last):
  File "/workplace/amazon-bedrock-workshop/test_client.py", line 3, in <module>
    bedrock = boto3.client('bedrock', region_name='us-east-1')

    return self._session.create_client(

    client = client_creator.create_client(

    service_model = self._load_service_model(service_name, api_version)
  File "/workplace/amazon-bedrock-workshop/.venv/lib/python3.9/site-packages/botocore/client.py", line 228, in _load_service_model

    raise UnknownServiceError(
botocore.exceptions.UnknownServiceError: Unknown service: 'bedrock'. Valid service names are: accessanalyzer,...  <truncated>

If I try to use the bedrock client in the utils directory instead by importing utils.bedrock in a python3 interactive session it complains that I need to install pydantic:

  File "/workplace/amazon-bedrock-workshop/utils/bedrock.py", line 5, in <module>
    from pydantic import root_validator
ModuleNotFoundError: No module named 'pydantic'

so I install it:

pip3 install pydantic

and it installed version 2.0.3. Then I tried again to import it and got a new error:

>>> import utils.bedrock
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/workplace/amazon-bedrock-workshop/utils/bedrock.py", line 66, in <module>
    class Bedrock:
  File "/workplace/amazon-bedrock-workshop/utils/bedrock.py", line 80, in Bedrock
    @root_validator()
  File "/workplace/amazon-bedrock-workshop/.venv/lib/python3.9/site-packages/pydantic/deprecated/class_validators.py", line 228, in root_validator
    raise PydanticUserError(
pydantic.errors.PydanticUserError: If you use `@root_validator` with pre=False (the default) you MUST specify `skip_on_failure=True`. Note that `@root_validator` is deprecated and should be replaced with `@model_validator`.

For further information visit https://errors.pydantic.dev/2.0.3/u/root-validator-pre-skip

If I change line 80 to look like this, that error goes away:

    @root_validator(skip_on_failure=True)

Then if I try to use the get_bedrock_client in that function, I'm back to the error where it doesn't recognize bedrock:

>>> import utils.bedrock
>>> bedrock = utils.bedrock.get_bedrock_client()
Create new client
  Using region: us-east-1
Traceback (most recent call last):

    bedrock_client = session.client(

    return self._session.create_client(
  File "/workplace/amazon-bedrock-workshop/.venv/lib/python3.9/site-packages/botocore/session.py", line 976, in create_client
    client = client_creator.create_client(
  File "/workplace/amazon-bedrock-workshop/.venv/lib/python3.9/site-packages/botocore/client.py", line 126, in create_client
    service_model = self._load_service_model(service_name, api_version)
  File "/workplace/amazon-bedrock-workshop/.venv/lib/python3.9/site-packages/botocore/client.py", line 228, in _load_service_model
    json_model = self._loader.load_service_model(
  File "/workplace/amazon-bedrock-workshop/.venv/lib/python3.9/site-packages/botocore/loaders.py", line 142, in _wrapper
    data = func(self, *args, **kwargs)
  File "/workplace/amazon-bedrock-workshop/.venv/lib/python3.9/site-packages/botocore/loaders.py", line 408, in load_service_model
    raise UnknownServiceError(
botocore.exceptions.UnknownServiceError: Unknown service: 'bedrock'. Valid service names are: accessanalyzer...<truncated>

So it looks like the versions of boto3 being downloaded by download_dependencies.sh are not working. Any advice would be appreciated.

I should note I'm trying to do this from VSCode this time. I previously got this working in SageMaker Studio with an earlier patched version of the boto3 and botocore modules. I'll go try Studio again and see if it helps.

[davetbo-amzn]

I just got it working in SageMaker Studio, so it must be something different in the environment.

Fixed the issue and marked the correct kernel type to use in SageMaker Studio.
Also added comments in the README to use conda environment.
Re-open the issue if you think it still persists.

Still encountering the following issues:

• pydantic install requirement is not documented (no string "conda" found in repo)
• on L106 of utils/bedrock.py: pydantic.errors.PydanticUserError: If you use @root_validator with pre=False (the default) you MUST specify skip_on_failure=True. Note that @root_validator is deprecated and should be replaced with @model_validator.
