ModuleNotFoundError: No module named 'joblib'

I’m not able to deploy my app on streamlit share. It is not able to find joblib. Please help me.
my github repo: Eclipse/streamlit_app at master · ArshKaushik/Eclipse · GitHub

Hi @ArshKaushik, welcome to the Streamlit community!

This is a subtle misfeature we’re working to solve…your requirements.txt file needs to be at the top-level of your repo; in your repo, the requirements.txt file is a streamlit_app/requirements.txt. So Streamlit sharing isn’t installing your dependencies, and thus, it can’t find joblib (or anything else).



I am facing the same issue. Found no way to move the requirements file up the stack as the files are automatically arranged in ascending order.


This isn’t a recommendation to change the sorting order of files, as that is likely operating system dependent. Rather, the recommendation is to have the file at the top-level of the file directory. Meaning, not having requirements.txt inside of a nested folder, but rather inside the repo without any other nesting.

Is there any update to resolve this issue or would you like to suggest an alternative to joblib.

Can you post a link to your code?

I have the same issue - even though streamlit says that it is installing joblib:

Collecting joblib==1.0.1
Downloading joblib-1.0.1-py3-none-any.whl (303 kB)

when building the app, it always runs into the error
ModuleNotFoundError: No module named 'joblib'

Hi @jonas-nothnagel -

In Streamlit sharing, it seems like it works (meaning, it doesn’t throw an error message), but locally I get the following:

(nlptest) rzwitch@threadripper:~/github_work/NLP-Project-Documents$ pip install -r requirements.txt 
Collecting en_core_web_sm
  Using cached en_core_web_sm-2.3.1-py3-none-any.whl
ERROR: Cannot install -r requirements.txt (line 16) and spacy==3.0.1 because these package versions have conflicting dependencies.

The conflict is caused by:
    The user requested spacy==3.0.1
    en-core-web-sm 2.3.1 depends on spacy<2.4.0 and >=2.3.0

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

Are you sure your dependencies are correct? I’ll also forward this on to our cloud team to see if they have any ideas.


This is a mistake indeed. It is weird that I did not get this error when deploying the app then.

It works perfectly locally, but when trying to share I always run into the joblib error as if the requirements are not even installed at all…

@randyzwitch on a personal note, would you mind to “unfork” my repo - not sure if I should share it yet, I just wanted to be ready for deployment :slight_smile:

Sure, but note that once your code is “in the wild”, it’s kinda too late. Keep that in mind if you share things on GitHub :slight_smile:

Hi @randyzwitch. You’re of course right, I was just waiting for the final approval (Which is there now) :slight_smile:
Anyhow, now the app was running once, but otherwise I always get the error:

ModuleNotFoundError: No module named 'joblib'

File "/usr/local/lib/python3.7/site-packages/streamlit/", line 332, in _run_script
    exec(code, module.__dict__)File "/app/nlp-project-documents/streamlit/", line 4, in <module>
    import joblib

Obviously this is not about joblib, it seems it simply does not install any of the libraries. If I uncomment
joblib at line 4, then it does not find pickle5 at line5 and so on. Again, it runs absolutely perfectly locally, but I would really like to share it now with others.

Any ideas what the issue could be if it works for you on streamlit share?

Hello, I am facing the same issue.
It fails when I run the import statement for joblib and my requirement file is on top in the main branch.

It shows its downloading: Downloading joblib-0.16.0-py3-none-any.whl (300 kB)

ModuleNotFoundError: No module named ‘joblib’


File "/usr/local/lib/python3.7/site-packages/streamlit/", line 333, in _run_script
    exec(code, module.__dict__)File "/app/capstone_592_project/", line 7, in <module>
    import joblib

Can you post the contexts of your requirements.txt file?

Thanks for responding. I found a solution to this problem.
I have created a packages.txt with the below lines in it and it worked.
