程序猿日常

Mac下安装python使用TensorFlow训练自己的模型

目标

https://www.tensorflow.org/lite/models/modify/model_maker/image_classification?hl=zh-cn

安装Python3.8版本

下载地址双击安装

安装pip

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

python3 get-pip.py

常用命令

卸载指定模块

pip3 uninstall ***模块名字

安装模块指定版本号

pip3 install --ignore-installed ***模块名字==版本号

安装模块 tflite-model-maker

pip3 install tflite-model-maker

安装brew

/bin/zsh -c "$(curl -fsSL https://gitee.com/cunkai/HomebrewCN/raw/master/Homebrew.sh)"

libusb-1.0.0.dylib (no such file) 安装libusb

brew install libusb

ImportError: cannot import name ‘array_record_module’ from ‘array_record.python’

git clone https://github.com/tensorflow/datasets /tmp/datasets

python3 -m pip install -e /tmp/datasets

运行 引用的模块正常

import os

import numpy as np

import tensorflow as tf

assert tf.__version__.startswith('2')

from tflite_model_maker import model_spec

from tflite_model_maker import image_classifier

from tflite_model_maker.config import ExportFormat

from tflite_model_maker.config import QuantizationConfig

from tflite_model_maker.image_classifier import DataLoader

import matplotlib.pyplot as plt

tf.keras.utils.get_file 加载网络数据集

image_path = tf.keras.utils.get_file(

'flower_photos.tgz',

'https://storage.googleapis.com/download.tensorflow.org/example_images/flower_photos.tgz',

extract=True)

image_path = os.path.join(os.path.dirname(image_path), 'flower_photos')

tf.keras.utils.get_file 加载本地数据集

file:/// 三个/从本地获取

image_path = tf.keras.utils.get_file(

'flower_photos.tgz',

'file:///Users/lang/Desktop/python/flower_photos.zip',

extract=True)

image_path = os.path.join(os.path.dirname(image_path), 'flower_photos')

数据集下载到默认缓存目录 ~/.keras

image_classifier.create 会报错 ssl证书验证失败

import ssl #全局取消证书验证

ssl._create_default_https_context = ssl._create_unverified_context #全局取消证书验证
