Dockerized WordPress on a Raspberry Pi
This blog runs on a a Raspberry Pi since 9th April 2019 and surprisingly the Pi performs quiete well. WordPress on itself does not need too many ressources for my use case since i don’t have hundreds of visitors per day, leaving capcaity for other applications.
The current setup includes an out of the box docker-compose and a backup script which uploads files to the dropbox cloud storage. In this series i would like to give you a short introduction how my setup works and how you could set it up by yourself.

PyTorch – expected scalar type Float but found Double
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…
Migrating existing OCI Kubernetes to VCN-Native Cluster with Terraform

Once upon a time i installed WSL 2 on Windows 10 correctly, run it and also worked with it. However, i was messing around with BlueStack, an android emulator which uses hyper-V. After configuring all the gears to make it…
Training languagemodel – RuntimeError the expanded size of the tensor (100) must match the existing size (64) at non singleton dimension 1.
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: RuntimeError the…
SentenceTransformer – float object is not subscriptable

Visual Explanation of Multi Head Attention
Why does changing the number of heads not change the number of parameters in the model? – That was the question i was asking myself. After drawing out the matrix multiplication and having gained the insight, i’d like to share…
How to evaluate the Transformer Trainer
If you initialized a Trainer object, it will do the training boiler plate for you. Using the TrainingArguments, you can additionally customize your training process. One important argument is the evaluation_strategy which is set to “no” by default, thus no…
Difference between the Tokenizer and the PreTrainedTokenizer class
I just got tossed into the cold water of the 🤗 Transformer framework and had some initial troubles with understanding the components. I’d like to write down my understanding of the Tokenizer and on how to add special_tokens to them,…
