Importerror: no module named typing error reporting solution (python2 PIP needs to be backed back from 21)

The default installation of PIP for python2 is version 21. This version is no longer supported, so an error is reported when executing pip. You need to back up the PIP version and execute the following command

curl -O https://bootstrap.pypa.io/pip/2.7/get-pip.py
python get-pip.py
python -m pip install --upgrade "pip < 21.0"

Mac Upgrade pip WARNING: You are using pip version 21.1.1; however, version 21.1.3 is available. You s

error:

You should consider upgrading via the ‘/usr/local/opt/[email protected]/bin/python3.9 -m pip install –upgrade pip’ command.

I also used the Windows upgrade method and found that it didn’t work, what a fucking headache!

The reason for this problem is that the versions of related packages such as CONDA and pip are too low to be updated automatically. Solution: enter the following command on the command line:

conda clean --all
conda update --all

Install:

pip install pyahocorasick -i HTTPS://mirrors.aliyun.com/pypi/simple/

The following are the errors I encountered during installation:

Recently, I was engaged in the knowledge mapping of natural language processing
but when building the system, I used a AC automaton word filtering , which is to remove sensitive words, such as

these sensitive words, which need to be replaced by some implied words or symbols such as * *. There are many ways to do this

- 1, AC automata
- 2, DFA filtering algorithm
- 3, replace filtering
- 4, regular expression filtering
for AC automata filtering, you need to use ahocorasick this library, now pyahocorasick

pip install pyahocorasick -i HTTPS://mirrors.aliyun.com/pypi/simple/

However, when installing pyahocorasick, it reported an error
that we need to install it

This is recommended to you error: Microsoft Visual C + + 14.0 is required. Get it with “Microsoft Visual C + + build tools, pro test 100% installation
it is offline installation, there will be no damage to the installation package;

The following is my successful installation of pyahocorasick:

Python 2.7: How to Install PIP

Python2 is no longer supported after PIP 2.1. Here you can use scripts to automatically download the highest supported version of PIP

1. Python2.7 the latest version of PIP installation file get-pip.py can be obtained by streaming

2. Install the file through Python 2.7

In the scripts folder, execute the following command to pull the get-pip.py file

curl https://bootstrap.pypa.io/pip/2.7/get-pip.py -o get-pip.py

After downloading, execute the file to install the latest version of PIP supported by python2.7

python get-pip.py

You can see that the PIP version of automatic installation is 20.3

  error: can't find Rust compiler

  If you are using an outdated pip version, it is possible a prebuilt wheel is available for this package but pip is not able to install from it. Installing from the wheel would avoid the need for a Rust compiler.

  To update pip, run:

      pip install --upgrade pip

  and then retry package installation.

  If you did intend to build this package from source, try installing a Rust compiler from your system package manager and ensure it is on the PATH during installation. Alternatively, rustup (available at https://rustup.rs) is the recommended way to download and update the Rust compiler toolchain.

  This package requires Rust >=1.41.0.

[Solved] Ubuntu18.04 Install pyqt5 error: Command “python setup.py egg_info“ failed with error code 1 in /tmp/pip-build-92

Error in installing pyqt5 on Ubuntu 18.04:
command “Python setup.py egg”_ info” failed with error code 1 in /tmp/pip-build-92ggdywh/PyQt5/

As a result, the version of PIP is too low. The default system version is pip9, so we need to update the PIP version
the update method is as follows:

python3 -m pip install --upgrade pip

Because most of the time, we install python, or apt install Python directly, resulting in the installation of python2.7. If you just want to use a version of python, such as python3, you can uninstall python2. It’s better to uninstall to avoid conflicts.

How to Solve Python WARNING: Ignoring invalid distribution -ip (e:\python\python_dowmload\lib\site-packages)

Recently, when using pip to install the plug-in, the following warning message appears:

WARNING: Ignoring invalid distribution -ip (e:\python\python_ dowmload\lib\site-packages)

resolvent:

Find the directory where the error is reported in the warning message, and then delete the folder at the beginning of ~. That kind of thing is caused by the plug-in installation failure/Midway exit, which leads to the plug-in installation exception. Although the warning message does not affect, it has obsessive-compulsive disorder. Just delete the folder:

As for why the above problems appear?

Because a few days ago, when I was using Python 3.9 to build the robot framework environment, I needed to install wxPython, and then when the latest fashion was installed, later when the robot framework ride was installed,

One of the components it depends on does not support the latest version, and the component it depends on does not support Python 3.9, so there was an exception when installing the plug-in.

The solution is to update python to 3, but I want to use 2.7, so this method does not work
Solution
I found that the version of pip is too high, and it is not compatible with python2, my version is pip21.1.3, so I need to set back the version of pip, the solution is as follows, just run it in order

curl -O https://bootstrap.pypa.io/pip/2.7/get-pip.py
python get-pip.py
python -m pip install --upgrade "pip < 21.0"

Perfect solution, PIP version back, install again without error correction

Problem Description:

it seems that the version of the library that has been adjusted for a long time has finally run through a LSTM demo, but if you want to open a new test file for testing, the following problems appear


Solution:

the solution to stackoverflow is to use the current keras library and tensorflow Library of unitall, because the higher version of keras library may be used, but the running code is of lower version. Note that you need to install tensorflow before installing keras

The specific steps of stackoverflow with the most likes are as follows:
delete tenorflow delete tenorflow

pip uninstall tensorflow

Update PIP version

pip install --upgrade pip

install keras

pip install Keras

install tensorflow

pip install tensorflow

Apart from this method, I want to say that my final solution is: I found the import statement of the keras library

from keras.models import Sequential
from keras.layers import LSTM, Dense, Activation

Cannot appear in two. Py files!!! Even if you just don’t use import, you will still report this error. It’s too bad. I found this problem after reloading it, so when testing the code, you should either create a new project or write the import statement in a file.

[Python] pip.vendor.urllib3.exceptions.readtimeouterror: httpsconnectionpool protocol

When installing a python module with pip or pychar, you sometimes encounter a readtimeout error. The reason for this problem is probably the network speed

my default source is Tsinghua, sometimes the link network is not good ( the day after the college entrance examination today, it is estimated that there are too many visitors, everyone wants to go to Tsinghua, ha ha ), so I change the source.

pip --default-timeout=100 install pyspark -i http://pypi.douban.com/simple/ --trusted-host pypi.douban.com

Perfect solution
