vscode+pytorch use experience record (personal record + irregular update)

1. Anaconda installation

I am learning the pytouch teaching of the small mound, so the anaconda installation is based on the master up. Students who need it can search "I am a mound" on their own B station to learn, he is pycharm+pytouch, so follow menot quite the same

python comes with anaconda, so we can call it directly without downloading it

I used python3.1 on my computer, I deleted it first to prevent the impact of anaconda installation

Find this and open it, and click on uninstall.

2.vscode+pytouch environment parameter configuration

①One is expansion, see the picture below

②Environment selection

③Add environment variables (I don't know if it's necessary, I still got it)

Follow your anaconda installation path, refer to mine

Remember to select Create and then browse, otherwise it will be replaced by others!!!

3. Try some source code found on the Internet

The code I ran also came from a small mound, and his class helped me get started quickly!!

Question:

At runtime, I get ModuleNotFoundError: No module named 'tensorboard'

In fact, there is a lack of tensorboard tools, just go to anaconda to download it

I use the Tsinghua mirror source, otherwise it will be slow to death

Open the anaconda prompt and enter the command

pip install tensorboard-i https://pypi.tuna.tsinghua.edu.cn/simple/

Wait for the installation, if prompted to update pip, follow his instructions to enter, and then re-enter the above installation instructions

In the end, please attach the domestic mirror source by the way. In fact, there are many online, so don't look for it.

①Domestic mirror image:

Alibaba Cloud http://mirrors.aliyun.com/pypi/simple/
Douban (douban) http://pypi.douban.com/simple/
Tsinghua University https://pypi.tuna.tsinghua.edu.cn/simple/
University of Science and Technology of China http://pypi.mirrors.ustc.edu.cn/simple/

②Change source command

Temporary: pip command + -i + mirror address.For example pip install numpy -i https://mirrors.aliyun.com/pypi/simple/

4. Install opencv

I am looking for some face recognition examples that need to use opencv, so I also tried the following tutorials, and the pro test is effective!

(11 messages) python installs opencv library anaconda virtual environment pytorch installs opencv_Ts_____'s blog-CSDN blog _pytorch installs opencv

Open the anaconda prompt directly, first enter the pytorch environment, then cd into the site-packages of the installation directory, refer to my

Then enter pip3 install opencv-python to install it (if the python version you installed is 2.x, remove 3)

Test it out:

Enter python, then import cv2, no error is reported

(I am an electronics student to learn machine learning neural network. I recommend the courses Mr. Wu Enda and Mr. Li Hongyi. There are corresponding courses at station b, and then pytouch can learn small mounds. I hope everyone can learn something, so do IRecently changed direction, need to use, Xiaobai learned it)
