No module named ‘PyEMD‘ ； Use plt figure()TypeError: ‘module‘ object is not callable

1, No module named ‘PyEMD‘

from PyEMD import EMD
eemd = EMD()
imf = eemd(data[target].values)
print(imf.shape)

Maybe the wrong reason ：

①pip install In the wrong

The first ⼀ Secondary derivative ⼊ There may be a mistake , Without this PyEMD This package , then ⼀ Then we will install the transmission ⼊ ：pip install PyEMD This is wrong

correct ：pip install EMD-signa

② It will continue to fail to find the module

Because our downloaded module name and our code import Is not the same , So we can't find it .
We downloaded PyEMD after , In our folder, his file name is ：pyemd
So we changed the name of the folder to PyEMD That's all right.

Method ： We just need to take anaconda Find the location of the installation library

First find your own installation Anaconda3 The location of ,
open envs Folder , Inside are all the virtual environments you installed .
Open a virtual environment folder you want to see .
open Lib, And on again site-packages
Here is the virtual environment , All libraries installed .

Maybe not , I'm in my windows download pyemd The above two steps are ok 了 . But in Linus The system has not ok.

then , Read other blogs . So I have to download these two packages ：numpy and scipy tool kit

therefore , I re deleted what I downloaded at the beginning . To download pip install msgpack-python;pip install msgpack

then pip install EMD-signal

Change the file name accordingly .
