QUESTION
I have a dataframe which has 4 columns- Name, Size, Text Extracted, Score. The score column contains a list with nan in it something like this
...ANSWER
Answered 2022-Mar-30 at 02:00From the look of it, it seems that your score column has usually a numerical result, but sometimes has a string
containing "[nan nan nan ...]"
rather than a list
of nan
.
One simple way to clean this up (here assuming an original DataFrame called df
) is:

...ANSWER
Answered 2021-Feb-16 at 21:55You need to save the model with a format, e.g. h5. I reproduced your error, fixed it with:
resnet.save("mymodel.h5")

Install keras-retinanet
In the repository, execute pip install . --user. Note that due to inconsistencies with how tensorflow should be installed, this package does not define a dependency on tensorflow as it will try to install that (which at least on Arch Linux results in an incorrect installation). Please make sure tensorflow is installed as per your systems requirements.
Alternatively, you can run the code directly from the cloned repository, however you need to run python setup.py build_ext --inplace to compile Cython code first.
Optionally, install pycocotools if you want to train / test on the MS COCO dataset by running pip install --user git+https://github.com/cocodataset/cocoapi.git#subdirectory=PythonAPI.
