esrgan-tf2 is a Python library typically used in Artificial Intelligence, Computer Vision, Deep Learning, Pytorch, Tensorflow, Generative adversarial networks applications. esrgan-tf2 has no bugs, it has no vulnerabilities, it has build file available, it has a Permissive License and it has low support. You can download it from GitHub.

:fire: ESRGAN (Enhanced Super-Resolution Generative Adversarial Networks, published in ECCV 2018) implemented in Tensorflow 2.0+. This is an unofficial implementation. :fire:. ESRGAN introduce the Residual-in-Residual Dense Block (RRDB) without batch normalization as the basic network building unit, the idea from relativistic GAN to let the discriminator predict relative realness, and the perceptual loss by using the features before activation. Benefiting from these improvements, the proposed ESRGAN achieves consistently better visual quality with more realistic and natural textures than SRGAN and won the first place in the PIRM2018-SR Challenge. Original Paper:   Arxiv   ECCV2018. Offical Implementation:   PyTorch.

            AttributeError: 'numpy.ndarray' object has no attribute 'unsqueeze'
            Asked 2021-Jul-09 at 17:24

            I'm running a training code using pyhtorch and numpy.

            This is the plot_example function:

            ...

            ANSWER

            Make sure image is a tensor in the shape of [batch size, channels, height, width] before entering any Pytorch layers.

            Here you have image=np.asarray(image)

            I would remove this numpy conversion and keep it a torch.tensor.

            Or if you really want it to be a numpy array, then right before it enters your generator make sure to use torch.from_numpy() as shown in this documentation on your numpy image before it gets unsqueezed: https://pytorch.org/docs/stable/generated/torch.from_numpy.html

            This function is ofcourse an alternative if you don't want to get rid of that original conversion.
