AttributeError: 'AbaqusCAEConfig' object has no attribute 'model_dump'

[ahashib]

Hello, I am a new user. I am trying to run an Abaqus model using Spyder. I downloaded the examples, but when I hit the run button in Spyder, I get an error - AttributeError: 'AbaqusCAEConfig' object has no attribute 'model_dump'. I would be grateful if anyone could kindly help.

You may have to upgrade pydantic to version >=2.0:

pip install pydantic>=2.0

Thank you Hailin, I have just upgraded it, but it still gives me the same error.

[haiiliin]

Can you show the pydantic package info using pip show pydantic?

[ahashib]

[haiiliin]

Seems that you did not upgrade your pydantic package to version 2.0 above

[ahashib]

Oh, sorry. Do I have to install in cmd?
I installed in the Spyder command window.

[haiiliin]

Maybe you installed it on a wrong Python interpreter that is not the one you are running the script

[ahashib]

Could you please suggest something? I am stuck with this for the last few days, tried to understand how it works reading documentation, and related discussions, but could not solve the problem.

1. I installed pyabaqus first. I didn't know that abqpy is the new version.
2. Then in the abqpy I saw a different command line to install abqpy. So, I tried one by one -
   2a) pip install abqpy
   After successfully installing it showed -
   warning: the script abqpy is installed in which is not on path
   consider adding this directory to PATH or, if you prefer to suppress this warning, use --no-warn-script-location
   2b) Then I installed pip install abqpy==2021.*
   After successfully installing it showed same error -
   warning: the script abqpy is installed in which is not on path
   consider adding this directory to PATH or, if you prefer to suppress this warning, use --no-warn-script-location
   2c) pip install -U abqpy==2021.*
   I have attached the last one here

You will have to upgrade your pydantic to version 2.0 above,

pip install pydantic>=2.0

the screenshot shows that you are using version 1.10.8

[haiiliin]

Anyway, I have released a new version 20**.6.2 that show be compatible with pydantic v1 and v2, please upgrade your abqpy version.

[haiiliin]

Try to install the package in cmd instead of the IPython console

[haiiliin]

If the specific Python directory is not added to the PATH environment variable, you just use the full path to access it in the command, e.g,

# Not cd C:\ProgramData\anaconda3\python.exe -m install abqpy
C:\ProgramData\anaconda3\python.exe -m pip install abqpy

You checked the working directory to C:\ProgramData\anaconda3:

cd C:\ProgramData\anaconda3

Then you can use:

# Not python.exe -m pip install abqpy
.\python.exe -m pip install abqpy

If one or more Python paths are added to the PATH environment variable, python will refer to the first one in the command line.

Could you tell me if there is any problem for the warning regarding PATH? I am using Spyder and it uses default Anaconda path for Python 3.11. I don't need to add abqpy in path for Python 3.12 as I am not using Python 3.12 anyways. Right?

Since the Scripts directory is not added to PATH, you cannot use abqpy command in cmd, but I guess you do not need it anyway, you can ignore this warning.

But seems like I installed it for Abaqus 2023. So, I again installed for Abaqus 2021 as Hailin stated in No. 2

Use this command without specifying a specific version and install the latest version of 2021:

C:\ProgramData\anaconda3\python.exe -m pip install -U abqpy==2021.*

Could you please tell what is this "U" for? Sometimes, I see it, sometimes I don't.)

-U is short to --upgrade, if you have installed a version of abqpy and you do not add this and, newer version will not be installed.

It says that access is denied. Could you please suggest how can i update pydantic for Anaconda Python 11? Is it
conda install pydantic -c conda-forge

See above:

C:\ProgramData\anaconda3\python.exe -m pip install pydantic>=2.0

In the whole time the Abaqus did not open, So, I think the abqpy package generated the job file. Does that mean Spyder could give me job file even if I don't have Abaqus installed in my PC?

No, abqpy use the abaqus command to submit the script to abaqus, if Abaqus is not installed, the abaqus command will not be available and the command will fail.

Thank you Hailin again for your constant support.
I don't know if I understood very well, but I tried to do all the things you said. The screenshot below says everything I did.

I was unable to upgrade pydantic, I guess. Please tell me if there is still anything I could do.

[haiiliin]

By installing abqpy 2021.6.2, pydantic v1 can be used, you don't need to upgrade it to v2

[haiiliin]

It seems that you don't have access to the Python interpreter, you can try to run cmd with the administrator.

Thank you Hailin for your time and effort in helping novice users.
