Help! Failed to install package 'filterpy'

Python Help
1

I am a beginner in python, and I have trouble installing package ‘filterpy’…

Environment: pip version: 24.0, python version: 3.8, OS: Win 10.0.19045.4170

At first, I tried to install Real-ESRGAN (GitHub - xinntao/Real-ESRGAN: Real-ESRGAN aims at developing Practical Algorithms for General Image/Video Restoration.) following the instruction:

# Install basicsr - https://github.com/xinntao/BasicSR
# We use BasicSR for both training and inference
pip install basicsr
# facexlib and gfpgan are for face enhancement
pip install facexlib
pip install gfpgan
pip install -r requirements.txt
python setup.py develop

The installation of basicsr was successful, but after typing pip install facexlib, an error occured:

It seems that I should install filterpy first. So I typed pip install filterpy, but almost the same error occurred:

I got confused because it said “No module named ‘filterpy’” when installing filterpy. I have tried to change the source of pip many times by pip config set global.index-url http://mirrors.cloud.tencent.com/pypi/simple.

I also tried to download the zip from pypi and used pip install D:\...\filterpy-1.4.5.zip, but just encountered the same error…

I tried to download the source code from github (GitHub - rlabbe/filterpy: Python Kalman filtering and optimal estimation library. Implements Kalman filter, particle filter, Extended Kalman filter, Unscented Kalman filter, g-h (alpha-beta), least squares, H Infinity, smoothers, and more. Has companion book 'Kalman and Bayesian Filters in Python'.) and used python setup.py install, and it said

Traceback (most recent call last):
  File "setup.py", line 4, in <module>
    import filterpy
ModuleNotFoundError: No module named 'filterpy'

Now I have no idea about what to do next…

I want to install the filterpy package correctly, and then install other requirements of Real-ESRGAN. Glad to hear any suggestion on this post, my English grammar and other aspects :slight_smile:

Maybe try using the default pypi index if possible?

https://pypi.org/simple

If it still doesn’t work, try again in a fresh venv: venv — Creation of virtual environments — Python 3.12.2 documentation should help with that

I’m not sure about this, so I’m asking Python Developers here: Does THIS version of Python have got different rules for locating packages than the newest version? Because I tried to install the OP’s package on my own and I didn’t get that error. I don’t remember that well but something tells me these rules was changed in the mean time.

As for You Brian, can you update your Python to a newer one? Or you have to work with this version?

Thanks for all helps above!

I changed the version of my python to 3.12.2(I didn’t use venv, but installed the newer version in another directory), and it worked. The installation of filterpy(and facexlib, which depends on filterpy) was successful, but I now encounter new problems…

As it says:

# Install basicsr - https://github.com/xinntao/BasicSR
# We use BasicSR for both training and inference
pip install basicsr
# facexlib and gfpgan are for face enhancement
pip install facexlib
pip install gfpgan
pip install -r requirements.txt
python setup.py develop

I need to install basicsr, facexlib and gfpgan. Now the installation of them is almost done, but pip warns me:

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
basicsr 1.4.2 requires lmdb, which is not installed.
gfpgan 1.3.8 requires lmdb, which is not installed.

So I typed pip install lmdb -i https://pypi.org/simple, then something went wrong:

      During handling of the above exception, another exception occurred:

Missing patch-ng? I’ve installed it!

Now I get a little crazy, is it normal to be so tough to deploy a working environment or install packages? Desparate to read your replies:)

Hmm, have you tried to install lmdb without patch_ng? The pip gives you a hint here:

py-lmdb: Using bundled liblmdb with py-lmdb patches; override with LMDB_FORCE_SYSTEM=1 or LMDB_PURE=1.

On Windows try:

set "LMDB_PURE=1" & pip install lmdb -i https://pypi.org/simple

On Linux:

LMDB_PURE=1 pip install lmdb -i https://pypi.org/simple

Hope that helps :hand_with_index_finger_and_thumb_crossed:

Thanks a lot! It works. Now the error is:

It seems I have to install MSVC++ 14.0 or so. Unfortunately the time is 21:30 here, so I may handle this problem tomorrow…

Thank you again for your reply :wink:
