The error message you're encountering seems to be related to a compatibility issue between PyTorch and the torch_sparse library, which is part of the torch-geometric package. Here's a breakdown of the key points from the error message and potential steps to resolve the issue:

  1. Error Source: The error occurs when trying to use torch.sparse_csc_tensor which is being called in the torch_sparse library but is not recognized as an attribute of the torch library in your current environment.

  2. Potential Cause: The version of PyTorch installed in your environment might not support torch.sparse_csc_tensor. This function is relatively new and is available in more recent versions of PyTorch.

  3. Resolution Steps:

    • Update PyTorch: Make sure that you are using a version of PyTorch that supports CSC (Compressed Sparse Column) tensor format. This feature is available in PyTorch versions 1.8 and later. You can update PyTorch using the following command: 
      conda activate rajnish
conda install pytorch=1.11.0 torchvision torchaudio cudatoolkit=11.3 -c pytorch
    • Check Compatibility: Ensure that all the packages, especially those related to PyTorch Geometric (torch_geometric, torch_sparse, etc.), are compatible with each other and with the version of PyTorch you are using. You may need to update these packages as well: 
      conda install torch-geometric=1.7.2 -c rusty1s -c conda-forge
    • Verify Environment: Sometimes, Python environments can get mixed up, especially if multiple versions of libraries are installed. Ensure that the correct environment is active and the correct paths are being used by Python.

  4. General Advice: After updating, verify the installation and the availability of torch.sparse_csc_tensor by trying to import it directly in a Python shell:

    import torch
print(dir(torch.sparse))  # Check if 'csc_tensor' is listed

These steps should help you resolve the issue. If the problem persists even after updating, there might be additional compatibility issues or installation errors that need to be addressed.

now i got this type of error:-

FileNotFoundError: [Errno 2] No such file or directory: 'pkl/best_model_cora1715767549.pkl'

now i got this type of error:-

FileNotFoundError: [Errno 2] No such file or directory: 'pkl/best_model_cora1715767549.pkl'

You just need to create a new folder named 'pkl' in the current directory to resolve this, and run the following command in the terminal.

     mkdir pkl
