TLDR: A dictionary in json treats all keys as string, while a python dict distinguishes not only between the content but also its datatype (see stackoverflow). When saving a dictionary into a json and reloading the dictionary from it, you have to be careful not to implicitely convert the original numeric key into a key …

I tried to implement a Flask Restful Endpoint with the webargs framework, which i already did back in 2020. Although, i copied the old code and made some tiny adjustments with the request call, i could not make it work in 2023. By asking ChatGPT for help, i gained a clearer understanding on all the …
TLDR: It is possible to dynamically create dags with only one dag script. However, at task execution the original dag script will be parsed once again. This results in unnecessary parsing iterations of dags, which are not the parent dag of the task at hand. Observation We have a script to dynamically create dags as …
TLDR: The default datatype of a numpy array translates to double/float64. If a Tensor is created from that array using torch.as_tensor it will adopt that datatype, which is not compatible with the default datatype of a neural network model which is float32. Using that tensor as input to the nn model will result in the …

Context I trained a new languagemodel from scratch using huggingface’ framework and a preconfiguration of Roberta Model on a custom dataset. Now i wanted to vectorize a new dataset using the pretrained model. Observation I receive an error: Resolution This error appears, because the languagemodel trained utilized a maximum document length of 64. However the …
TLDR: np.nan objects are of type float Observation I was trying to apply the SentenceTransformer (v2.2.0) on a list of custom documents to create embeddings for each of them, however i would get the error “TypeError: ‘float’ object is not subscriptable“. The traceback refered to the tokenize function, so let’s have a closer look. Explanation …

Sometimes when editing a post or a page in Wordpress, the site just crashes with the error “The editor has encountered an unexpected error.” Let’s take a deeper look and try to fix this problem.
A deployed pod is stuck in pending status. Looking deeper into the pod a warning appears: 0/3 nodes are available: 3 node(s) had no available volume zone.
We observed a problem where dags did not run at the specified time at all but consistently started at a random time. Let’s dig into it.
If you want to mount a PVC to your k8 cluster to persist data of your pgadmin deployment, you will likely get a mount permission denied error.
