QUESTION
I am trying to build an app from a python file (Mac OS) using the py2app extension. I have a folder with the python file and the "setup.py" file.
- I first tested the app by running
python setup.py py2app -A
in the terminal and the dist and build folder are successfully created and the app works when launched. - Now when I try to build it non-locally by running the command
python setup.py py2app
in the terminal, there are various "WARNING: ImportERROR" messages while building and finally aerror: [Errno 2] No such file or directory: '/opt/anaconda3/lib/python3.8/site-packages/rtree/lib'
error.
How can I fix this? I've tried to delete anaconda fully as I don't use it but it seems to still want to run through it. Additionally, I have tried to run the build command using a virtual environment but I end up having even more import errors.
*I Left out a lot of the "skipping" and "warning" lines using "..." for space
ANSWER
Answered 2022-Mar-13 at 16:13The error error: [Errno 2] No such file or directory: '/opt/anaconda3/lib/python3.8/site-packages/rtree/lib'
was caused by py2app trying to build the program bundle using a non-existent interpreter. This means that even if you try to uninstall a manager like Anaconda, it still has option logs somewhere on your mac.
The fix:
- Open the terminal and type the command
type -a python
.
- You will see similar lines

...ANSWER
Answered 2022-Mar-01 at 17:47So in case anyone comes across similar for any reason with me encountering this probably due getting a new machine and IT doing their voodoo magic transferring my old stuff to this new machine.
Anyhow, there were a bunch of things I still needed to install after I got my new machine and i am not able to exactly pin point what caused issues from my question but in the end I was able to resolve. Follow me there below ...
Checking out my python.exe files I found 2 paths. First one added as environment variable
- C:\Users-----\AppData\Local\Programs\Python\Python310
- C:\Users----\AppData\Roaming\Python\Python310\
Second one not added. Adding roaming version to path variables did not solve the issue and gave additional errors instead:
Fatal error in launcher: Unable to create process using '"C:\Program Files\Python310\python.exe"
So
I uninstalled python (done that before didnt help doing just that alone)
Deleted all environment variables pointing to python (here is what environment variables are just in case - https://www.computerhope.com/issues/ch000549.htm)
Uninstalled python extension from VS code (https://marketplace.visualstudio.com/items?itemName=ms-python.python)
Deleted Python folders mentioned in the two paths above
Then reinstalled python (clicked add to path during installation)
Reinstalled VS code python extension
Everything works now.
Best of luck
QUESTION
I have a local python project called jive
that I would like to use in an another project. My current method of using jive
in other projects is to activate the conda env for the project, then move to my jive
directory and use python setup.py install
. This works fine, and when I use conda list
, I see everything installed in the env including jive
, with a note that jive
was installed using pip.
But what I really want is to do this with full conda. When I want to use jive
in another project, I want to just put jive
in that projects environment.yml
.
So I did the following:
- write a simple
meta.yaml
so I could use conda-build to buildjive
locally - build jive with
conda build .
- I looked at the tarball that was produced and it does indeed contain the
jive
source as expected - In my other project, add jive to the dependencies in
environment.yml
, and add 'local' to the list of channels. - create a conda env using that environment.yml.
When I activate the environment and use conda list
, it lists all the dependencies including jive
, as desired. But when I open python interpreter, I cannot import jive
, it says there is no such package. (If use python setup.py install
, I can import it.)
How can I fix the build/install so that this works?
Here is the meta.yaml, which lives in the jive
project top level directory:
ANSWER
Answered 2022-Feb-05 at 04:16The immediate error is that the build is generating a Python 3.10 version, but when testing Conda doesn't recognize any constraint on the Python version, and creates a Python 3.9 environment.
I think the main issue is that python >=3.5
is only a valid constraint when doing noarch
builds, which this is not. That is, once a package builds with a given Python version, the version must be constrained to exactly that version (up through minor). So, in this case, the package is built with Python 3.10, but it reports in its metadata that it is compatible with all versions of Python 3.5+, which simply isn't true because Conda Python packages install the modules into Python-version-specific site-packages
(e.g., lib/python-3.10/site-packages/jive
).
Typically, Python versions are controlled by either the --python
argument given to conda-build
or a matrix supplied by the conda_build_config.yaml
file (see documentation on "Build variants").
Try adjusting the meta.yaml
to something like
QUESTION
What I am playing around with right now is to work with PyTorch within a pipeline, where all of the preprocessing will be handled.
I am able to make it work. However, the results I am getting are a bit off. The loss function seems to be not decreasing and gets stuck (presumably in local optima?) as the training loop progresses.
I follow the standard PyTorch training loop and wrap it inside the fit method as this is what sklearn wants:

Answered 2021-Oct-18 at 08:46In statsmodels formulae, you need to quote your variables (i.e. columns in your dataframe) when they contain special characters such as -
. Have a look at the documentation, your term "x-axis" is interpreted as "x" - "axis". Quoting variable can be done with the Q()
transformation. Make sure to quote the variable name inside with different (single/double) quotes that you use for the string:

I want to deploy a machine learning model and have the environment yml file and the model pickle file. When I include scikit-learn=0.23.2
to the dependencies, conda automatically uninstall this scikit-learn version and install scikit-learn-0.24.2
. Therefore, I get the following warning when I load the pickle file.

...ANSWER
Answered 2021-Aug-13 at 16:38Whatever is in the pip:
section of a Conda environment YAML gets installed after the Conda environment is created, and is run with the pip install -U
command. The -U
gives Pip the permission to upgrade any existing packages if it is necessary to install the specified packages. In this particular case, the version of imblearn
must be incompatible with the scikit-learn
version you have selected.
imblearn
Technically, you should be using imbalanced-learn
not imblearn
, as stated in the package description. That also means you don't even need to install from PyPI, since imbalanced-learn
is available through Conda Forge.
If you require having scikit-learn=0.23
then you must use imbalanced-learn=0.7
. This should be under the regular dependencies, not in the pip:
section.

Install patsy
You can use patsy like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
