Moviepy: TypeError: 'float' object cannot be interpreted as an integer

[WDBell]

I'm new to moviepy.

clip = VideoFileClip("Rough Guide to Dublin (54).mp4")

I tried three mp4 files, all with the same result. Fuller information:

>>> clip = VideoFileClip("Sailing Mediterranean - 7 Sardinia.mp4")
Traceback (most recent call last):
  File "<interactive input>", line 1, in <module>
  File "C:\Python34\lib\site-packages\moviepy\video\io\VideoFileClip.py", line 82, in __init__
    nbytes = audio_nbytes)
  File "C:\Python34\lib\site-packages\moviepy\audio\io\AudioFileClip.py", line 63, in __init__
    buffersize=buffersize)
  File "C:\Python34\lib\site-packages\moviepy\audio\io\readers.py", line 70, in __init__
    self.buffer_around(1)
  File "C:\Python34\lib\site-packages\moviepy\audio\io\readers.py", line 234, in buffer_around
    self.buffer =  self.read_chunk(self.buffersize)
  File "C:\Python34\lib\site-packages\moviepy\audio\io\readers.py", line 123, in read_chunk
    self.nchannels))
TypeError: 'float' object cannot be interpreted as an integer

Suggest this change to code (and hope that this is a reasonable place to post this). In readers.py, substitute the second result = statement.

    def read_chunk(self,chunksize):
        #~ chunksize = int(round(chunksize))
        L = self.nchannels*chunksize*self.nbytes
        s = self.proc.stdout.read(L)
        dt = {1: 'int8',2:'int16',4:'int32'}[self.nbytes]
        result = np.fromstring(s, dtype=dt)
        #~ result = (1.0*result / 2**(8*self.nbytes-1)).\
                                 #~ reshape((len(result)/self.nchannels,
                                          #~ self.nchannels))

        result = (1.0*result / 2**(8*self.nbytes-1)).\
                                 reshape((int(len(result)/self.nchannels),
                                          self.nchannels))

        #self.proc.stdout.flush()
        self.pos = self.pos+chunksize
        return result

I'm having the same problem. Looks like reshape is expecting an integer, but it gets a float because Python 3 does not auto convert floats to integers in division unless you use //.

I may open a PR

This will be resolved when #384 is merged.

[laventura]

Hi, I get the same error on moviepy when I try to read an .mp4 file.
This was working code (back in Dec 16, 2016).

Is there an official resolution to this yet? Or should I just fix it locally as suggested by @WDBell (which seems to work).

Thanks

@laventura #384 will be part of the repo in the next update.

[zippau]

I have the same issue. @Gloin1313 any idea when it will be updated next?

[mbeacom]

@zippau It's merged into master and being pushed to pypi this morning.

[earney]

Can this issue be closed?

[earney]

closing.. please reopen if the issue arises again!

[hahnsangkim]

I had the same issue and solved it by updating numpy as follows:
conda update --prefix yourenvs anaconda

[Techlucy]

Hello I have got the same problem now. I am using Python 3.5.2 |Anaconda custom (64-bit). Any help Thanks.

[tburrows13]

@Techlucy Have you got the latest version of moviepy? Run pip3 install moviepy --upgrade to get the latest version.
Or run, as @fido2478 suggests conda update --prefix yourenvs anaconda.

[Techlucy]

Well me I am using it on Training neural network with Tensorflow. However I have corrected the error by installing the numpy 1.11.0 version.

I consulted this repository

[lfiaschi]

I can confirm @Techlucy I have this error with numpy 1.12.1, fixed installing numpy 1.11.0

[tjacobs]

Still getting this error after running

pip3 install moviepy --upgrade

and it installed

What to do?

[nerdogram]

Still getting this error: TypeError: 'float' object cannot be interpreted as an integer

Did something else (Numpy?) change?

[tburrows13]

It is a very common error in Python programming. You'll have to give the full traceback if you want help with it. It could be anywhere.

[FrancescoScarlata]

I'm having the same problem i think. I'm trying to use the lib heatmappy so i don't know all the code yet, but looks like the error is out of my control. Below there is the traceback.

[sandracor]

Hello,

list1 = []
for i in range(0, len(final_seq)):
list1.append(np.mean(final_seq[i].reshape(-1,2.1157586473643497), axis=1))

final_seq = np.array(list1)

I got the Error:'float' object cannot be interpreted as an integer
hat can I do against it?
