No module named Boto3 error

[wisemanleo]

I’m following this workflow here for automatic invoice processing:

Automatic Invoice Processing using Amazon Textract through Boto3 – jy_amz

I have installed Anaconda 3, and have ran the Anaconda command prompt to run the command:
python -m pip install boto3

The workflow runs successfully until the Python Script node, where I get the following error:

ERROR Python Script 3:3 Execute failed: No module named ‘boto3’
Traceback (most recent call last):
File “”, line 23, in
ModuleNotFoundError: No module named ‘boto3’

Apologies in advance if I’m missing something simple. From my end, it looks like I’ve installed all the packages I needed.

@wisemanleo my recommendation would be to install miniconda and use a YAML file provided by KNIME and maybe edit it to use only conda-forge and include boto3 or install it later via the prompt. Make sure you have the right environment activated:

Which Python versions works better with Knime?

@JayR the thing is you will have to find the right combination of Python version and packages that would work with KNIME as well as your individual packages What I would do install Miniconda on your system (how to manage environments) Choose a major Python version (like 3.8) that would most likely work with you package look up a suitable YML file provided by KNIME (python version and operating system) edit the file so it would suite your initial needs. Use only ‘conda-forge’ and add additiona…

conda install -c conda-forge boto3

Thanks - I missed the YML part. Passed those issues now, thank you! Now the new issue :

ERROR Python Script 3:3 Execute failed: ‘Textract’ object has no attribute ‘analyze_expense’
Traceback (most recent call last):
File “”, line 31, in
File “C:\ProgramData\Anaconda3\envs\py36_knime\lib\site-packages\botocore\client.py”, line 601, in getattr

AttributeError: ‘Textract’ object has no attribute ‘analyze_expense’

@wisemanleo

AttributeError: ‘Textract’ object has no attribute ‘analyze_expense’

Maybe you have to install that also. Not sure if this is a dependency that should have been installed automatically:

conda install -c conda-forge textract

You might want to check if Python 3.6 is the right version for you you could try and use 3.9 which should be supported by KNIME-. I would list all the packages you need in a YAML file and maybe create a new Environment. Anaconda or Miniconda should make sure that the versions would match. Sometimes there can be differences even between the standard Anaconda and conda-forge repositories. So maybe stick to one. I prefer to use conda-forge since at the moment it also appears to be the ‘free’ version.

Amazing. I think I’m almost there - now have this credentials issue, which I thought was already addressed in the first part of the workflow. I’m googling at the moment on how to address the following:

ERROR Python Script 3:3 Execute failed: Unable to locate credentials

Got the Python Script working - I had to install Amazon CLI and input my credentials in Command Prompt.
