[英]In python, how to add command to bash_profile?
My enviroment is Google Colab, which is in Python. 我的环境是Google Colab,它是用Python编写的。 I am trying to follow the instructions on this website. 我正在尝试按照本网站上的说明进行操作。
https://github.com/abisee/cnn-dailymail https://github.com/abisee/cnn-dailymail
And it mentions to 它提到了
Then add the following command to your bash_profile: 然后将以下命令添加到bash_profile:
export CLASSPATH=/path/to/stanford-corenlp-full-2017-06-09/stanford-corenlp-3.8.0.jar
My best guess was to run using 我最好的猜测就是继续使用
!export CLASSPATH=/stanford-corenlp-full-2017-06-09/stanford-corenlp-3.8.0.jar !export CLASSPATH = / stanford-corenlp-full-2017-06-09 / stanford-corenlp-3.8.0.jar
Which executed without any errors 哪个执行没有任何错误
But then the instructions say to 但随后说明说
You can check if it's working by running 您可以通过运行检查它是否正常工作
echo "Please tokenize this text." | java edu.stanford.nlp.process.PTBTokenizer
So I tried 所以我试过了
!echo "Please tokenize this text." | java edu.stanford.nlp.process.PTBTokenizer
But then I got this error 但后来我得到了这个错误
Error: Could not find or load main class edu.stanford.nlp.process.PTBTokenizer
Caused by: java.lang.ClassNotFoundException: edu.stanford.nlp.process.PTBTokenizer
Edit: 编辑:
I found instructions to install Java in colab 我找到了在colab中安装Java的说明
# Install Java
!apt-get install -y openjdk-8-jdk-headless -qq > /dev/null
os.environ["JAVA_HOME"] = "/usr/lib/jvm/java-8-openjdk-amd64"
!java -version
But 但
!echo "Please tokenize this text." | java edu.stanford.nlp.process.PTBTokenizer
Still gives the same error 仍然给出相同的错误
I'd recommend not changing your .bash_profile
as you're going to accumulate settings and junk. 我建议不要更改你的.bash_profile
因为你要累积设置和垃圾。
Instead, java lets you specify CLASSPATH with the -cp
option, which we can add to the Python script. 相反,java允许您使用-cp
选项指定CLASSPATH,我们可以将其添加到Python脚本中。
(You can also use java -cp /path/to/blahblah.jar etc
to test it as their instructions recommend.) (您也可以使用java -cp /path/to/blahblah.jar etc
按照他们的说明进行测试。)
Change this line in make_datafile.py to: 将make_datafile.py中的这一行更改为:
command = ['java', '-cp', '/path/to/blahblah.jar', 'edu.stanford.nlp.process.PTBTokenizer',
'-ioFileList', '-preserveLines', 'mapping.txt']
If you're still having trouble, make sure you have a valid jar! 如果您仍然遇到问题,请确保您有一个有效的罐子!
List the contents with: 列出内容:
jar -tvf /path/to/blahblah.jar
You should see edu/stanford/nlp/process/PTBTokenizer.class
listed, otherwise no amount of messing with the CLASSPATH will fix it. 你应该看到列出了edu/stanford/nlp/process/PTBTokenizer.class
,否则没有任何搞乱CLASSPATH的东西会修复它。
