Introduction

I often got this error message when I learning about machine learning by Python, recently.

'Object arrays cannot be loaded when allow_pickle=False'

The reason for this message is actually very clearly. In fact, it’s just that “allow_pickle” is adjusted to False after Numpy package is upgraded.

And it caused us to be hindered when reading some pickle-encapsulated training data.

Introduction

If you are familiar with the deep learning and its environment, you may often hear “CUDA“. Before we starting to train our model, maybe we need to install GPU driver, CUDA and cuDNN toolkits. They can make our training have the best effect.

PyTorch is a famous Python deep learning framework

Introduction

I have been studying about pointer-generator network lately, and I found a package “pkbar“can let us to use keras style progress bar in our tasks.

In fact, it can be used not only in the code of PyTorch framework but also in any loop.

Today when I reading the document of the “Transformers” package which Hugging Face developed, I suddenly discovered the model I build, its state is “eval()”, not “train()”. It seems that as long as we use “from_pretrained()” method is the default state “eval()”.

This is very common error message in PyTorch.

When I using PyTorch to train a model, I often use GPU_A to train the model, save model. But if I load the model I saved to test some new data, I always put the new data in a different GPU, we called it GPU_B.

When we using the famous Python framework: PyTorch, to build our model, if we can visualize our model, that’s a cool idea.

In this way, we can check our model layer, output shape, and avoid our model mismatch.

I think if we use Pytorch framework to train a model, the commonly error messages are “Model mismatch” and the following error:

Today, when I using PyTorch to build a LSTM model, I got an error occured:
