How to install PyCaret in AWS Glue

Asked 2021-Jul-08 at 17:01

How can I properly install PyCaret in AWS Glue?

Methods I tried:

--additional-python-modules and --python-modules-installer-option
Python library path
easy_install as described in Use AWS Glue Python with NumPy and Pandas Python Packages

I am using Glue Version 2.0. I used --additional-python-modules and set to pycaret as shown in the picture.

Then I got this error log.

Python Make UMAP fast(er)

Asked 2021-Jul-06 at 03:01

I am using UMAP (https://umap-learn.readthedocs.io/en/latest/#) to reduce the dimensions in my data. My dataset contains 4700 samples with 1,2 million features each (which I would like to reduce). However, this takes quite a while despite using 32 CPUs and 120GB RAM. Especially the construction of the embedding is slow and the verbose output did not change in the last 3.5 hours:

With 1.2 million features and only 4700 samples you are going to be better off just precomputing the full distance matrix and passing that in with metric="precomputed". Currently it is expending a lot of work computing nearest neighbors of those 1.2million long vectors. Just brute force will be a lot better.

QUESTION

How do I solve "incompatible numba" error while installing Scanpy?

Asked 2021-Mar-21 at 14:47

I tried installing the Scanpy package on Jupyter with "pip install Scanpy" but I got the the errors below;

ERROR: pynndescent 0.5.2 has requirement numba>=0.51.2, but you'll have numba 0.48.0 which is incompatible. ERROR: umap-learn 0.5.1 has requirement numba>=0.49, but you'll have numba 0.48.0 which is incompatible

When I tried to separately install an upgraded version of numba, I got the error below;

ERROR: Cannot uninstall 'llvmlite'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.

you can try install with pip install -c numba numba=0.51.2.1rc1 if it doesn't work for you alternativly install RUN pip install llvmlite --ignore installed before pip install numba. HAVE A GOOD DAY:)

Package updates from remote git repository are not reflected in site-packages

Asked 2021-Mar-17 at 09:06

I have been trying to upgrade a package based off of the most recent changes on git but the changes aren't taking effect. I ran several variations of this command, such as also using python -m pip and the actual path to the pip version in anaconda, as well as adding --upgrade: pip install git+git://github.com/lmcinnes/umap@master

Here is the output each time:

ANSWER

Answered 2021-Mar-17 at 09:06

try using the --update and --force-reinstall options of pip, or:

pip install --update --force-reinstall git+git://github.com/lcminnes/umap@master
