No module named 'thinkstats2'

[jfulghum]

Hi! When I copy and paste the provided nsfg.py script in Atom or Spyder I get following error:

File "preg.py", line 11, in import thinkstats2 ImportError: No module named 'thinkstats2'

Why is there no module named thinkstats2? Thank you!

[AllenDowney]

If you just copy and paste that script, you won't have the data files or the supporting Python modules. Instructions for working with the code are in the Preface:

http://greenteapress.com/thinkstats2/html/thinkstats2001.html#sec3

Hope that helps.

i am facing the same issue. I have anaconda installed per the instructions, however i am still getting the module not found error for thinkstats2 - ModuleNotFoundError: No module named 'thinkstats2'. can anyone help fixing this issue?

[AllenDowney]

thinkstats2.py is in the ThinkStats2 repository, so if your IDE looks in that directory, you should find it.

The alternative is to

pip install thinkx

The thinkx package contains the files you need for all of the Think books, including thinkstats.py. If you pip install it, it should be on your Python search path.

Hope that helps! Allen

Thank you so much, Allen. I tried the pip install thinkx option and it worked. Ii don't get that issue any more, however, i am getting a new issue - I am getting the below file not found error. I checked at the main function, it looks fine, i tried to run everything separately. I dont get any errors but also can't get the code print "All Test Passed" at the end as well. I am stuck and any help or direction will be greatly appreciated.

FileNotFoundError Traceback (most recent call last)

in () 163 164 if __name__ == '__main__': --> 165 main()

[AllenDowney]

This is another version of the same issue. If your IDE is not in the ThinkStats directory, it won't find the data files. You will have to figure out how to get your IDE to look in that directory, or change the code to specify the entire path to the data file.

I'm having the same issue. So frustrating, . I find the hard thing with learning python, is not learning, writing code, writing scripts at the start but dealing with these types of issues . Perhaps they go hand in hand. ;

[arvindbetrabet]

This is my experience on a laptop with, Ubuntu 16.04, Anaconda installed, Spyder 3.2.7, Python 3.6.4. Downloaded the ThinkStats2 repository from github as a zip, to an external HD in my case, extracted/un-zipped the file. Using the terminal I "cd"ed to the code folder (after un-zipping the repo from github, the folder structure is the same as on github). Invoked the Spyder IDE, $Spyder at the terminal prompt when it came up navigated to the code directory and opened the nsfg.py and nsfg2.py and clicked on "Run file" the green triangle button. The file ran without any issue, there was a warning 'sys' imported but not used, I commented that line out and ran the file without any errors.

Hope that helps.

BTW, the same process can be used to start the Jupyter $jupyter notebook

This will open a Jupyter UI instance in FireFox and you will see all the ,ipynb files in the code folder

[AllenDowney]

Thanks, that is very helpful. For people who are familiar with the Command Window, that is the way to go.

[RasikaBI]

@arvindbetrabet , can you please help me its still not working for me. I am using Windows 10. I have all the files in (shared by Allen) in my download folder. I am using jyputer notebook. Not sure how to do it. I tried using command line, copied nfsg and nfsg2.py on Python27 folder and tried running it. Its still not working it gives me the same error again and again : Error 163 164 if name == 'main': --> 165 main()

Please help me

[AllenDowney]

That error is very surprising. What file are you running, how are you running is, and is there an error message?

It seems like you might not be familiar with your software development environment, so starting with Think Stats might not be a good choice.

[violet4]

in the error you provided, I noticed it says

if name == 'main':

instead of

if __name__ == '__main__':

(I now see it could be a github formatting thing.......... you can make the formatting work properly by adding a line above the code and a line below the code, and on each of those lines place three backticks ("`")). unless python 2 is different from python 3 for that, that looks like a bug (I mostly only use python 3). if you typed that by hand, it's a better idea to copy-paste the whole error message and add the backticks as I mentioned.

I recommend the command line. I don't remember how to open the command line on windows but it should be easy enough to find by google. I think windows uses "chdir" instead of cd (mac and linux use "cd"). "chdir" to "path/to/ThinkStats2/code", where "path/to" should be replaced by the correct path. for example, for me on mac, it's "cd /Users/mica/git/ThinkStats2/code". maybe for you it will be something like "chdir C:\myname\Downloads\ThinkStats2". note that you should have the entire ThinkStats2 repository, not just copying individual files. the files work together, so they all need to be there in the structure that is provided from this repository. the point of chdir'ing/cd'ing to that directory is that python and all the files you're running can find each other properly. if I were to do "cd /Users/mica ; python /Users/mica/git/ThinkStats2/code/nsfg.py" , it would probably fail because nsfg would try to "import somemodule", expecting somemodule to be in the current directory, but it wouldn't find it because it's in /Users/mica/git/ThinkStats2/code/, not in my current directory /Users/mica.

if you are just trying to run nsfg.py and nsfg2.py as recommended by the book, then from that directory just run "python nsfg.py" and then "python nsfg2.py". then when you are ready to work with the jupyter notebooks, run "jupyter notebook" (again it should be from that directory), which by default, should open that directory in the default browser in the jupyter notebook interface. I don't remember how to deal with paths in windows. you might have to type the full path to "jupyter" for it to work, e.g. "C:\path\to\anaconda\bin\jupyter" (with the correct path to anaconda). mine is "/Users/mica/anaconda3/bin/jupyter", but that bin is on my path when I've sourced the anaconda environment so all I have to type is "jupyter notebook".

It seems like you might not be familiar with your software development environment, so starting with Think Stats might not be a good choice.

as Professor Downey mentioned, learning how to do these python things does take some time. I recommend finding one of those books that introduces you to python - usually the first chapter or so will teach a little bit about this stuff.

[RasikaBI]

@mica5 : let me try the suggestions given by you thank you so much

[RasikaBI]

@AllenDowney : Thank you for the reply.i started with Python a month back.. these errors are similar to the errors mentioned above by others. I am unable to run these files on my windows 10.

[arvindbetrabet]

Hi RasikaBI, I have anaconda (https://www.anaconda.com/download/#windows) installed on my Windows 10 laptop, with python version 3.4.4.

I used spyder IDE instead of jupyter notebook (notebooks are mainly used for interactive coding, plotting and creating markdown reports that can be exported as html and sent to folks who want the reports). Please use spyder for learning python (since you mentioned that you are new to python).

When spyder IDE was up and running, I navigated to where I had downloaded the code for the Think Stat book (the code folder) and opened both nsfg.py and nsfg2.py and was able to run both the files.

Hope that helps.

[chris-kehl]

This is a small maybe even irrelevant question, but is anyone using the anaconda vscode with these tutorials? I’ve used it to start out with the nsfg.py files seems to work great.

[armannp]

Hi! When I copy and paste the provided nsfg.py script in Atom or Spyder I get following error:

File "preg.py", line 11, in import thinkstats2 ImportError: No module named 'thinkstats2'

Why is there no module named thinkstats2? Thank you!

Hey! I've faced this problem too. The point is that first, you need to download THINKX. For installing packages you will need PIP INSTALL to do it easily. So, first of all, make sure that you have the latest version of pip in your OS. Then, in an environment in which you are working, use this command: pip install thinkx. If you work with Anaconda you should open the terminal in Jupyter then run above command. if you work with python IDE, you should open terminal of your os (in mac).

Finally, you will be able to run nsfg.py... Actually be aware of the location of your data such as this file: dct_file='2002FemResp.dct', You should put the Thinkstats2 file in the right path.

[akweteyisaac]

Hello, I am using pycharm and after adding content root and downloading thinkx I am still getting this

FileNotFoundError: [Errno 2] No such file or directory: '2002FemPreg.dct'

[Ajasahib]

pip install thinkx solved the issue for me. Windows 10 Anaconda jupyter lab

[Flash100775]

I have Anaconda, Jupyter and Thinkstats2 all installed but when I click on nsfg.py it opens up in a python window not Jupyter. When I try and run it in the python window it opens up python shell but nothing happens. I cut and paste the full programme into Jupyter but again when I run it nothing happens. Can anyone help?

[arvindbetrabet]

nsfg.py, as i understand it is a helper module, so if you read the code it is for reading the data from NSFG - National Survey of Family Growth. It has function definitions for doing that, the only two statements I can see are the print statements that will produce any output, which I am able to replicate when I run the nsfg.py via the command line.

As such Jupyter notebook can only open a file with a .ipynb extension, the .py file can be executed via command line or in an IDE like Spyder.

I can see the code in IDLE but when I select Run Module a Python Shell window opens but nothing happens and I dont see the output of a print statement. So I am still stuck.

Thanks for the offer of help. Much appreciated. However I think I resolved the problem. I moved the Thinkstats2 downloads into the Anaconda file path and that seems to have worked. I ran the code in IDLE and the tests passed.
