AttributeError: module 'tensorflow.python.keras.utils.generic_utils' has no attribute 'populate_dict_with_module_objects'
Problem and solution:

This happened several times as of recent. Some env gets messed up and I end up with most tests failing with:

I think it's conda installing a broken tensorflow, I'm not 100% sure - see the solution in the next comment.

### Solution

If you encounter the same, here is how to fix it:

```
pip uninstall -y tensorflow-gpu tensorflow
pip install tensorflow-gpu -U 
```
(I assume you want the gpu version - adjust if not)
<|||||>I think that for the last few versions, when installing `tensorflow` you get a `tensorflow` that can use your GPU out of the box, so there's no need to play with `tensorflow-gpu`/`tensorflow`!<|||||>I think it's another package's dependency pulling in `tensorflow-gpu` - e.g. I see: `wandb/requirements.txt:tensorflow-gpu==2.3.1`<|||||>In my case, after `conda install tensorflow-gpu` - to install `tensorflow` version 2.2,
I then tried `pip install autokeras` (because conda does not have this package). 
`pip` would install **_another_** `tensorflow`  (in this case, version 2.3).

And this is when the problem happened.

```

```
It seems like we have similar error.
I am not sure  what you have done with your env but your solution worked in my case too, obviously.<|||||>Please add the snippet of the code into the program of general_utils.py

**1. Find out your path**

For me, the path is listed as follows:

/home/user/miniconda3/lib/python3.7/site-packages/tensorflow/python/keras/utils/generic_utils.py

**2. Paste the code into the program of generic_utils.py**
```
def populate_dict_with_module_objects(target_dict, modules, obj_filter):
  for module in modules:
    for name in dir(module):
      obj = getattr(module, name)
      if obj_filter(obj):
        target_dict[name] = obj
```

**3. Initialize the dev tool**
It will be working after initializing  the dev tool (it is Terminal for me in Linux)
