日常记录沙雕操作

1.2019-5-57：安装好anaconda3找不到conda命令：
echo 'export PATH="/code/anaconda3/bin:$PATH{"}^{\prime }>>/.bashrcsource/.bashrcconda–v2.2019-5-31:ImportError:Nomodulename{d}^{\prime }net{s}^{\prime }vim/.bashrcexportPYTHONPATH=$PYTHONPATH:/code/anaconda3/lib/python3.5/site-packages/tensorflow/models/research:/code/anaconda3/lib/python3.5/site-packages/tensorflow/models/research/slim
source ~/.bashrc

3.自己下载数据集：
注释相关操作，直接bash
4.出现找不到什么文件 ：直接把文件路径设置为绝对路径就行了，应该能够解决大部分的问题
5.jupyter 密码被莫名其妙修改： jupyter notebook passwd,强行覆盖修改配置文件中的密码
6. ImportError: libSM.so.6: cannot open shared object file: No such file or directory
ImportError: libXrender.so.1: cannot open shared object file: No such file or directory
ImportError: libXext.so.6: cannot open shared object file: No such file or directory
解决：apt-get install libsm6
apt-get install libxrender1
apt-get install libxext-dev

7. ImportError: libgthread-2.0.so.0: cannot open shared object file: No such file or directory
   apt-get update
   apt-get install libglib2.0-dev
8. ERROR: Unexpected bus error encountered in worker. This might be caused by insufficient shared memory (shm).
   nvidia-docker run -e NVIDIA_VISIBLE_DEVICES=0,1 -p 7000:7000 -it --rm -v /mnt/cjy/code:/code --ipc=host docker.local/2018140256/dockerfile/road_extraction:torch1.1.0-1
9. THCudaCheck FAIL file=/pytorch/aten/src/THC/THCGeneral.cpp line=383 error=11 : invalid argument
   I actually just solved it compiling pytorch from source. Might be useful for someone else having the same problem
10. RuntimeError: cannot join current thread
    安装4.19版本
    11.ValueError: num_samples should be a positive integer value, but got num_samples=0
    没有读进图
    12.查看分盘情况
    lsblk
    ========看到学弟的博客。。。想起来我还有个这个东西，写两句，写两句
    娘诶。。。发现这篇不知道是什么时候的
    开始瞎写来

1.安装h5py ：https://stackoverflow.com/questions/29831052/error-importing-h5py
sudo pip install cython
sudo apt-get install libhdf5-dev
sudo pip install h5py

2.ImportError: No module named pywt
pip install PyWavelets

3.服务器的GUI界面远程打开
Xming + putty

4.from pip import main ImportError: cannot import name ‘main’
vi /usr/bin/pip3
from pip import main //这行也要修改
if name == 'main’:
sys.exit(main.main())//增加__main_._

5.安装提速
python -m pip install torch==0.4.0 torchvision -i https://pypi.tuna.tsinghua.edu.cn/simple

6.重启服务 docker
Sudo systemctl daemon-reload
Sudo systemctl restart docker

7.docker: Error response from daemon: create nvidia_driver_430.14: error looking up volume plugin nvidia-docker: plugin “nvidia-docker” not found.
解决 sudo service nvidia-docker start

8.查看磁盘信息
sudo hdparm -I /dev/sda

9.容器网络端口暴露：nvidia-docker run -e NVIDIA_VISIBLE_DEVICES=0,1,2,3 -it --rm -v /home/cjy:/code --ipc=host --network host docker.local/2018140256/dockerfile/road_extraction:torch1.0-cuda10-cudnn7-tensorboard

10. RuntimeError: element 0 of tensors does not require grad and does not have a grad_fn
    from torch.autograd import Variable as V
    loss = StableBCELoss()(logits, V(labels.float(),requires_grad=True))
    AttributeError: module ‘yaml’ has no attribute ‘FullLoader’
    解决：安个yaml

11.下面这个是tensorflow和cudnn版本兼容的系列错误，懂得都懂，我就瞎写，不懂的就用torch吧
ERROR: tensorflow-gpu 1.14.0 has requirement tensorboard<1.15.0,>=1.14.0, but you’ll have tensorboard 1.13.1 which is incompatible.
ERROR: tensorflow-gpu 1.14.0 has requirement tensorflow-estimator<1.15.0rc0,>=1.14.0rc0, but you’ll have tensorflow-estimator 1.13.0 which is incompatible.
查看cudnn环境
cat /usr/local/cuda/include/cudnn.h | grep CUDNN_MAJOR -A 2

ImportError: libcudnn.so.7: cannot open shared object file: No such file or directory
https://github.com/tensorflow/tensorflow/issues/20271
Error : Failed to get convolution algorithm. This is probably because cuDNN failed to initialize, so try looking to see if a warning log message was printed above.
https://github.com/tensorflow/tensorflow/issues/24828
直接换tensorflow的版本以及cudnn的版本不对

12.报错：bool value of Tensor with more than one value is ambiguous
解决：
loss_function=nn.MSELoss #错误
loss_function=nn.MSELoss()#正确

13.报错：SyntaxError: non-default argument follows default argument
解决：将带默认值的放在无默认值的前面，换一下位置就行了

14.报错：RuntimeError: copy_if failed to synchronize: device-side assert triggered
解决：标签设置为0-1

有记得的就这么多，剩下不记得的遇到了再说。

====================问：如何能让自己心态好一点？=
