Issues with TensorFlow and Keras installation - DeepLearning

Hello everyone,

I hope you’re all doing well. I’m currently in the process of learning about deep learning, specifically image classification, using the cat and dog classification workflow.

I’ve been encountering some difficulties with installing TensorFlow and Keras libraries. I’ve attempted installation via KNIME by creating a new environment, trying both CPU and GPU options. However, I’m consistently facing errors such as “library not installed correctly” or “Keras library missing”.

Furthermore, I’ve also tried manual installation using the Conda browser, but I still encounter the same error messages.

Here are a few screenshots of the error messages

These issues are primarily related to the installation of Keras and TensorFlow libraries. In addition to this, I’m experiencing another problem concerning the usage of the workflow, specifically with the Keras Network Learner node.

Previously, the node could execute with a message indicating a missing library, but now I’m unable to execute the workflow at all due to a different error message:

" Errors loading flow variables into node : Training data converter ‘org.knime.ip.dl.DLImgPlusValueToFloatTensorConverterFactory’ of network input ‘input10:0’ could not be found. Are you missing a KNIME extension? "

I would greatly appreciate any guidance or suggestions on resolving these issues. If anyone has encountered similar problems or has insights into potential solutions, I would be very grateful for your assistance.

Thank you in advance for your help.
