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.

Linux is an operating system that can do all the functions you imagine

Introduction

For a long time, if we want to use Linux OS to connect to Windows with graphic user interface, we have many choices, such as Chrome remote, Teamviewer, RDP … etc.

Today I want to record how to configure Linux to use RDP software to connect to Windows. At the beginning, I want to say that these two different operating systems might be in conflict with each other, and they are not so easy to configure. In fact, it takes less than 20 minutes to configure.

So, let’s go.

Today I saw the news and found the sudo tool commonly used in unix-liked operating systems has a heap overflow BUG (number CVE-2021-3156).

At present, it has been confirmed that full root permissions can be obtained in the following version:

Ubuntu 20.04（sudo 1.8.31）
Debian 10（sudo 1.8.27）
Fedora 33（sudo 1.9.2）\

According the news, as well as several discussion forums I have roughly read, almost all of them are suggesting that everyone quickly upgrade the package version. This bug was be found in 2021/01 and was notified to the sudo development group.

After a week, the new version of the fix was already online.

And then, I record how to upgrade our sudo package version.

Introduction

When we using Chrome browser, sometimes if we went to HTTP website, the browser will redirect to the HTTPS website. (I’m not sure other browser will help us to do it)

Sure, if it can help us to redirect the SSL website is better, but when we are develop a new website and we need to test it step by step, redirect to HTTPS website is trouble. It may be make us can’t test our website.

Python is the most popular programming language!

Introduction

Everyone is familiar with the compressed file. These compressed file means that we compress one or more files and folders into a file, which is also call archiving.

In addition to archiving, according to the different compression format algorithms, some can even compress the file size to help us better store and transmit these files.

But what if we need to restore the compressed file back to the original file? At this time, we need to decompress according to different compression formats.

Today I want to record how to use Python module zipfile to compress or decompress some fiile as ZIP format.

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.

Introduction

Those who are familiar with natural language processing (NLP) must be familiar with Glove and Python package Gensim.

Glove（Global Vectors for Word Representation）is a paper published by Stanford NLP Group, and it is also an open source pre-trained word embedding model. The Glove that you often see on the Internet now refers to this open source pre-trained model.

Gensim is a Python implementation of the Word2Vec paper proposed by Google in 2013, allowing us to easily train the word vector model using our own corpus via this package.

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.
