AttributeError: 'int' object has no attribute 'dtype'

Hello,
I am trying to run your graph visualization on the vision transformer from the CoCa model.
Here is the code I run and the full traceback I get.

Code

model,_, processor = open_clip.create_model_and_transforms(
            model_name="coca_ViT-L-14",
            pretrained="mscoco_finetuned_laion2B-s13B-b90k",
            device=device)
inputs = (torch.rand([1, 3, 224, 224]),)
ep = torch.export.export(model.visual, inputs) 
model_explorer.visualize_pytorch('visionnet', exported_program=ep,
                                port=8081)

Traceback

Any help appreciated,

Hi @mat10599,

I was not able to replicate your issue ... so this likely means this is an environmental issue:

Here's the script I ran:

import model_explorer

import torch


device = "cpu"

model,_, processor = open_clip.create_model_and_transforms(
            model_name="coca_ViT-L-14",
            pretrained="mscoco_finetuned_laion2B-s13B-b90k",
            device=device)
inputs = (torch.rand([1, 3, 224, 224]),)
ep = torch.export.export(model.visual, inputs) 
model_explorer.visualize_pytorch('visionnet', exported_program=ep,
                                port=8081)

Here's how to recreate my conda environment:

conda create -n model-explorer python=3.11
conda activate model-explorer
pip install ai-edge-model-explorer open_clip_torch

While conda is not necessary, I do recommend you have a way of separating your environments/starting fresh ones. Is your environment similar? Are there any discrepancies you can see? Are you using a GPU/Cuda? Thanks.

Hello,

Thank you for your quick reply,

The error happens both when I load the model on cuda and cpu.

I am using vertex ai workbench VMs and torch 2.2 (torch 2.3 is not available yet) is installed by default during VM creation.
The problem is most probably due to the torch version. It's hard for me to check in local with torch 2.3 as I am on windows and on the office computer...
I am on python 3.10 which might be another cause ...

Hi @mat10599, do you have access to WSL or can you install/use WSL on your windows machine? Just to get more data... I will see if I can setup a vertex AI workbench to try.

[pkgoogle]

Ok I have setup a new vertex AI workbench... in a fairly standard configuration (I kept the jupyterlab3 image... did you?), It already has conda installed, so I just went to the terminal and did this:

pip install ai-edge-model-explorer open_clip_torch

This effectively installed torch 2.3.1 in my case.. how did you create your vertex AI workbench instance?

I can free myself some time to try this over the weekend but visualisation is more a nice to have for me than a key component.

Regarding you second comment, when I create an environment, tensorflow/pytorch is pre-installed during vm creation and setup wrt the gpus. I have been advised to apply this method to avoid driver gpu issues.

(see screenshot below for the pre-installed environment that are available, torch 2.2 is the latest)

[pkgoogle]

Ok, I'm guessing my account type is different so I have different options... do you know if you have a clean environment you can select? I'm thinking you can just do the installation steps on a cleaner environment so your software will use the right versions. Alternatively, have you just tried manually updating PyTorch?

With GPU & conda:

conda install pytorch torchvision torchaudio pytorch-cuda=12.1 -c pytorch -c nvidia

or
With GPU & pip:

pip3 install torch torchvision torchaudio
