cupy-cuda114 v10.6.0 AttributeError: module 'cupy.cuda.cudnn' has no attribute 'getConvolution2dForwardOutputDim'

Description

In this article, we will explore the issue of AttributeError: module 'cupy.cuda.cudnn' has no attribute 'getConvolution2dForwardOutputDim' when using the cupy-cuda114 version 10.6.0. This error occurs when trying to access the getConvolution2dForwardOutputDim function from the cupy.cuda.cudnn module.

To Reproduce

To reproduce this issue, you can create a simple Python script using the cupy library and try to access the getConvolution2dForwardOutputDim function. Here is an example script:

import cupy as cp
import cupy.cuda.cudnn as cudnn

print(dir(cudnn))
print(cp.__version__)
print(cp.cuda.runtime.runtimeGetVersion())
print(cp.cuda.cudnn.getVersion())

Running this script will output the list of available functions in the cupy.cuda.cudnn module, the version of cupy, the CUDA runtime version, and the CUDA cuDNN version. However, when you try to access the getConvolution2dForwardOutputDim function, you will get the AttributeError.

Installation

To install the cupy-cuda114 version 10.6.0, you can use the following command:

pip install cupy-cuda114==10.6.0

Environment

To set up the environment for this issue, you can follow these steps:

  1. Initialize a new Python virtual environment using uv init:
uv init cupy_cuda114_py310 --python 3.10
  1. Activate the virtual environment:
cd cupy_cuda114_py310/
uv run python --version
  1. Install the cupy-cuda114 version 10.6.0 using uv add:
uv add cupy-cuda114
  1. Install the cudnn library using cupyx.tools.install_library:
uv run python -m cupyx.tools.install_library --cuda 11.4 --library cudnn
  1. Verify that the cudnn library is installed correctly by checking the CUDA_PATH environment variable:
echo $CUDA_PATH
  1. Copy the cudnn.h header file and the libcudnn.so library to the correct locations:
sudo cp ~/.cupy/cuda_lib/11.4/cudnn/8.4.0/include/cudnn.h $CUDA_PATH/include
sudo cp ~/.cupy/cuda_lib/11.4/cudnn/8.4.0/lib/libcudnn.so* $CUDA_PATH/lib64
  1. Run the cudnn_hello_world.py script to verify that the cudnn library is working correctly:
uv run python cudnn_hello_world.py

Additional Information

After investigating this issue, it appears that the getConvolution2dForwardOutputDim function is not available in the cupy.cuda.cudnn module for the cupy-cuda114 version 10.6.0 This function is actually available in the cupy.cuda.cudnn module for the cupy-cuda11 version 11.0.0 and later.

To overcome this issue, you can try the following solutions:

  1. Upgrade to a newer version of cupy that supports the getConvolution2dForwardOutputDim function.
  2. Use a different library or framework that provides the getConvolution2dForwardOutputDim function.
  3. Implement the getConvolution2dForwardOutputDim function manually using the cupy library.

Conclusion

In conclusion, the AttributeError: module 'cupy.cuda.cudnn' has no attribute 'getConvolution2dForwardOutputDim' issue occurs when using the cupy-cuda114 version 10.6.0. This issue can be overcome by upgrading to a newer version of cupy that supports the getConvolution2dForwardOutputDim function, using a different library or framework that provides the getConvolution2dForwardOutputDim function, or implementing the getConvolution2dForwardOutputDim function manually using the cupy library.

Q&A

Q: What is the issue with the cupy-cuda114 version 10.6.0?

A: The issue is that the getConvolution2dForwardOutputDim function is not available in the cupy.cuda.cudnn module for the cupy-cuda114 version 10.6.0.

Q: Why is the getConvolution2dForwardOutputDim function not available?

A: The getConvolution2dForwardOutputDim function is not available in the cupy.cuda.cudnn module for the cupy-cuda114 version 10.6.0 because it is not supported by the CUDA cuDNN version 8.4.0 that is included with this version of cupy.

Q: What can I do to overcome this issue?

A: There are several solutions to this issue:

  1. Upgrade to a newer version of cupy: You can try upgrading to a newer version of cupy that supports the getConvolution2dForwardOutputDim function.
  2. Use a different library or framework: You can try using a different library or framework that provides the getConvolution2dForwardOutputDim function.
  3. Implement the getConvolution2dForwardOutputDim function manually: You can try implementing the getConvolution2dForwardOutputDim function manually using the cupy library.

Q: How do I upgrade to a newer version of cupy?

A: To upgrade to a newer version of cupy, you can use the following command:

pip install cupy-cuda114==11.0.0

This will install the cupy-cuda114 version 11.0.0, which supports the getConvolution2dForwardOutputDim function.

Q: How do I use a different library or framework?

A: To use a different library or framework, you will need to install it and then import it in your code. For example, you can use the tensorflow library, which provides the getConvolution2dForwardOutputDim function.

Q: How do I implement the getConvolution2dForwardOutputDim function manually?

A: To implement the getConvolution2dForwardOutputDim function manually, you will need to use the cupy library to calculate the output dimensions of a convolutional layer. This can be done using the following code:

import cupy as cp

def get_convolution2d_forward_output_dim(input_shape, filter_shape, stride):
    output_height = (input_shape[0] - filter_shape[0]) // stride + 1
    output_width = (input_shape[1] - filter_shape[1]) // stride + 1
    return output_height, output_width

This function takes the input shape, filter shape, and stride as input and returns the output height and width.

Q: What are the system requirements for cupy-cuda114?

A: The system requirements for cupy-cuda114 are:

  • CUDA 11.4 or later
