error UnicodeDecodeError: 'utf-8' codec can't decode byte 0xff in position 0: invalid start byte

Resize float32 array with K-nearest neighbour in the same way as scipy.misc.imresize or tf.image.resize

What if Batch Normalization is used in training mode when testing?

Python tries to convert a byte-array (a bytes which it assumes to be a utf-8-encoded string) to a unicode string (str). This process of course is a decoding according to utf-8 rules. When it tries this, it encounters a byte sequence which is not allowed in utf-8-encoded strings (namely this 0xff at position 0).

Since you did not provide any code we could look at, we only could guess on the rest.

From the stack trace we can assume that the triggering action was the reading from a file (contents = open(path).read()). I propose to recode this in a fashion like this:

QUESTION

Resize float32 array with K-nearest neighbour in the same way as scipy.misc.imresize or tf.image.resize

Asked 2019-Oct-15 at 11:48

I am to create a network using much of the same characteristics as pix2pix: https://github.com/affinelayer/pix2pix-tensorflow.

My adjustment is that I will not be using images, but matrices with float32 values. This introduces a lot of problems and there is a lot to rewrite. Most of the code can easily be rewritten, but I've encountered a problem.

The network has a separable convolutional layer where the image is resized using tf.image.resize. This function uses different resize methods, such as K-Nearest Neighbors, and I don't want to loose that feature. Both scipy.misc.imresize and tf.image.resize are limited to int values and does not support any higher than uint16. If I were to transform the data to said formats, I will loose precision.

Is there a way to create this efficiently in numpy (or any equivalent) supporting float32?

Sorry for not introducing any code, but the problem more or less explains itself without (I hope).

Try using scipy.ndimage.interpolation.zoom. This works for float number images. Use it as below:

image = scipy.ndimage.interpolation.zoom(image, 0.5)

QUESTION

What if Batch Normalization is used in training mode when testing?

Asked 2019-Jan-07 at 09:51

Batch Normalization has different behavior in training phase and testing phase.

For example, when using tf.contrib.layers.batch_norm in tensorflow, we should set different value for is_training in different phase.

My qusetion is: what if I still set is_training=True when testing? That is to say what if I still use the training mode in testing phase?

The reason why I come up with this question is that, the released code of both Pix2Pix and DualGAN don't set is_training=False when testing. And it seems that if is_training=False is set when testing, the quality of generated images could be very bad.

Is there someone could please explain this? thanks.

During training, the BatchNorm-layer tries to do two things:

estimate the mean and variance of the entire training set (population statistics)
normalize the inputs mean and variance, such that they behave like a Gaussian

In the ideal case, one would use the population statistic of the entire dataset in the second point. However, these are unknown and change during training. There are also some other issues with this.

A work-around is doing the normalization of the input by
