Jupyter notebook 死内核

Question

I was doing a project in Colab. But when I copy the same code in my jupyter notebook in my MacBook, I get a dead kernal message when I run the following imports.

import os
import random
import numpy as np
import matplotlib.pyplot as plt
import matplotlib.patches as patches
from matplotlib.font_manager import FontProperties
import scipy
import cv2
%matplotlib inline

np.random.seed(2)

from sklearn.metrics import confusion_matrix
import itertools

from keras.utils.np_utils import to_categorical
from keras.models import Sequential
from keras.layers import Dense, Dropout, Flatten, Conv2D, MaxPool2D, BatchNormalization
from tensorflow.keras.optimizers import RMSprop
from keras.preprocessing.image import ImageDataGenerator
from keras.callbacks import ReduceLROnPlateau, ModelCheckpoint
from keras.models import model_from_json

import warnings

warnings.filterwarnings('ignore')

Any Ideas on how to fix this?

Answer 1

It seems conda has not installed properly in your system. Try again by uninstalling the anaconda and install it back from scratch.

Please check thislink to install Anaconda.

After installing Anaconda in your system, Create virtual environment to install Tensorflow in it as below:

To install the current release of CPU-only TensorFlow,

conda create -n tf tensorflow
conda activate tf

Or, to install the current release of GPU TensorFlow

conda create -n tf-gpu tensorflow-gpu
conda activate tf-gpu

You can also create virtual environment in Anaconda Environment section. Open the Jupyter notebook by selecting the same virtual environment.

run below code:

conda install pip
pip install tensorflow

After doing all these setups, your code may run fine as I have already executed above code in Jupyter and its not showing any error.
