Can't install tflite-model-maker from pip or github
@MartinKlefas 
Sorry for the late reply. Could you please try to install using  `pip install tflite-model-maker` with python 3.8. I was able to install the tflite-model-maker with python 3.8. Please refer to the below screenshot:

And also please refer to the similar [issue](https://github.com/tensorflow/tensorflow/issues/59323) and let us know if it helps.

Thank you!
 Thanks for the suggestion, this time it got a lot further than usual, and didn't download all the nightly builds, but I did still end up with the below error:

Full install log is here: https://1drv.ms/t/s!AjAaK-BVbphXliztpWTdIGmr3Kf3?e=O5nb8I If I follow the suggestion in the other issue and install with `--no-dependencies` then pip complains about missing dependencies next time I need a package, and the example code won't run.

I'm using the same code on a docker though that came with pre-installed tflite model maker - so I know it's this conda environment, and not the code that's the problem. Hi, I was able to install `tflite_model-maker` and `tflite-model-maker-nightly` using pip without any errors. 
Please find the gist attached [here](https://colab.sandbox.google.com/gist/sachinprasadhs/5ef2dab8f4ed8636eae3368120f35061/59855.ipynb) for reference. Thanks! Thanks for the update. In almost all your pip lines it states: Requirement already satisfied
My install still failed from a completely clean conda environment though. Pip still could not work out which of the various dependent packages to use. Maybe it's because I'm on windows or something??

Please see attached the full log below - far too much to paste into this box, but suffice to say it's a fail.
[tflite model maker install.txt](https://github.com/tensorflow/tensorflow/files/11157832/tflite.model.maker.install.txt)
 I'm getting requirement already satisfied because I ran the `tflite_model-maker` in same session before trying nightly.

To understand more about the issue, could you please create a new conda environment using `conda create -n venv_name`
and install pip using `conda install pip` and try again installing `pip install tflite_model-maker` OK, doing that will result in the even worse errors of my first post, because it'll be python 3.11.2 that gets used. It'll take an hour or so to fail, and will download hundreds of tf_models_nightly packages with dates at the end of their names. I'll post back the results shortly. I was wrong, it took a little under an hour, and output 1382 lines before hitting an error. As mentioned though, when not specifying a lower version of Python it tries installing every daily build.

[Python 3.11.2 install log](https://github.com/tensorflow/tensorflow/files/11221760/install_log.txt)

Today when I made another completely fresh python 3.8 environment it seems to have installed successfully, which is a first. It didn't use any nightly packages, but still needed to test hundreds of different packages for compatibility and took over 20 minutes to do the install - and my computer is reasonably well specced.

Anyway despite it looking like it worked, some of the python import lines still seem to fail:

`np.object` was a deprecated alias for the builtin `object`. To avoid this error in existing code, use `object` by itself. Doing this will not modify any behavior and is safe.
The aliases was originally deprecated in NumPy 1.20; for more details and guidance see the original release note at:
    https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations`
 Same problem for me, in a google colab notebook  Another nice way to do this within colab notebooks is to clone the tensorflow repo and then modify the requirements.txt file so you can control the versions of packages installed.  Had a few errors, but was able to modify versions and everything worked fine.  Make sure you remove the -q flag so you can get the verbose output to find where the dependency errors are.

Clone the repo:
!git clone https://github.com/tensorflow/examples.git

Navigate to the directory with the setup.py script
cd examples/tensorflow_examples/lite/model_maker/pip_package

Install tflite-model-maker and the required dependencies
!pip3 install -e .

If there are errors, modify the requirements.txt file in the model maker dir - when running verbose it will tell you where the error is
and you can modify accordingly.  
examples/tensorflow_examples/lite/model_maker

Then keep running (!pip3 install -e . )until there are no errors and you'll be good to go.
 I had this same issue using python 3.10 so I tried to use 3.8. Then I hit a new issue with the `orbax` package which was recently renamed.

Creating a new conda environment with python 3.9 successfully installed without issue.
```
conda create -n object-detection python=3.9
conda activate object-detection
pip install tflite-model-maker
``` The installation of the tflite-model-maker with the pip command keeps crashing on Google Colab. Either due to requirements not being found, or the disk running out of space. As a result, cannot complete the Flower Classification tutorial. > I had this same issue using python 3.10 so I tried to use 3.8.

Worked for me! Thanks, man! > The installation of the tflite-model-maker with the pip command keeps crashing on Google Colab. Either due to requirements not being found, or the disk running out of space. As a result, cannot complete the Flower Classification tutorial.

I'm having the same issues, tried updating pip but it didn't help, I also tried reverting to python 3.9 on my own machine but the program still has problems with the _numba_ version, the required one would be the 0.53 but that particular version is not available > > The installation of the tflite-model-maker with the pip command keeps crashing on Google Colab.

Try installing numba 0.53.0 with: pip install numba==0.53.0 
This version works with python 3.9 > > > The installation of the tflite-model-maker with the pip command keeps crashing on Google Colab. Either due to requirements not being found, or the disk running out of space. As a result, cannot complete the Flower Classification tutorial.

I also got the issue where it tried downloading a million nightly builds. I tried installing this version of numba but got this

`Failed to build numba llvmlite
ERROR: Could not build wheels for numba, llvmlite, which is required to install pyproject.toml-based projects` Yo, @StainlessStlRat ,
You can always clone the tflite-model-maker repo and troubleshoot by modifying the 'requirements.txt' file (this is in the model_maker directory). That way as missing dependencies come up you can modify as needed or install versions of packages with conflicts. The big one to change is the scann version to scann==1.2.8.  There are a couple of others that will cause issue, but I'll leave that to you.

Link to pypi: https://pypi.org/project/tflite-model-maker/0.4.3/

git clone https://github.com/tensorflow/examples
cd examples/tensorflow_examples/lite/model_maker/pip_package
pip install -e .

I only imported the tflite_model_maker packages and confirmed they import properly, but did not run any of the examples. That said, this worked as of an hour ago. @ldiangelis 
whats your python version? are u running in docker? whats the runtime arch? Linux x86_64?
I figured there is no way to run model-maker on m1 chips unless you run in docker I finally busted out my old Mac and followed the guide and got it to work, but I can't believe I didn't think to run it in Docker. Is there a pre-built image for that? I already trained my models but of course will need to do it again in the future. - I was not able to install model maker lib on differnt docker images (mostly older ubuntu)
- Based on other threads and commentary I got a feeling that tensorflow is not being actively maintained (dead?)
- Trying pytorch approach I did manage to use tensorflow lite inside colab by modifying the requirements.txt contained in the model training tutorial. 
I am not sure if this can help since the last time I worked on that piece of software was six months ago.

Here is my [requirements.txt](https://github.com/FilippoGuarda/Colabs/blob/main/requirements.txt) file

> * Based on other threads and commentary I got a feeling that tensorflow is not being actively maintained (dead?)

 yeah, it looks like tensorflow lite has been left on the sideline for a while.

I tried:

git clone https://github.com/tensorflow/examples
cd examples/tensorflow_examples/lite/model_maker/pip_package
pip install -e .

but this fails with:

This is all on a clean anaconda environment - the pip command is the first I've run in it.
