            timesteps_mixed_outer = tf.concat([timesteps_mixed_outer, [timesteps_mixed_inner]], axis = 0)

            You have to check the shape of timesteps_mixed_outer and timesteps_mixed_inner. try to change the axis value.

            or try this.

            You probably have CUDA11 install on your system. Tensorflow 1.X can't run on CUDA 11 unless you use Docker and Nvidia Container Toolkit.

            I recommend you to use a Docker container provided by Tensorflow with the required version.

            Difference between channel_shift_range and brightness_range in ImageDataGenerator (Keras)?
            Asked 2022-Jan-02 at 07:27

            There are multiple pages (like this and this) that present examples about the effect of channel_shift_range in images. At first glance, it appears as if the images have only had a change in brightness applied.

            This issue has multiple comments mentioning this observation. So, if channel_shift_range and brightness_range do the same, why do they both exist?

            ...

            ANSWER

            Answered 2021-Dec-31 at 04:47

            Channel shift and Brightness change are completely different.

            Channel Shift: Channel shift changes the color saturation level(eg. light Red/dark red) of pixels by changing the [R,G,B] channels of the input image. Channel shift is used to introduce the color augmentation in the dataset so as to make the model learn color based features irrespective of its saturation value. Below is the example of Channel shift from mentioned the article: In the above image, if you observe carefully, objects(specially cloud region) are still clearly visible and distinguishable from their neighboring regions even after channel shift augmentation.

            Brightness change: Brightness level of the image explains the light intensity throughout the image and used to add under exposure and over exposure augmentation in the dataset. Below is the example of Brightness augmentation: In the above image, at low brightness value objects(eg. clouds) have lost their visibility due to low light intensity level.

            Install keras-preprocessing

            You can install using 'pip install keras-preprocessing' or download it from GitHub, PyPI.
            You can use keras-preprocessing like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
