Typically, your intentions should determine which programming language you should pick up as each language (without a loss of generality) provides some benefits over others for specific types of tasks.

However, since your question is specifically related to Deep Learning, I would recommend Python as it is the most trending language for Deep Learning. The reasons for this are:

Also, TensorFlow comes with extensive tutorials aimed at users of different levels of expertise. You can learn DL and immediately relate whatever you've learnt to code by following their examples.

I completely agree with M. Basak recommendation concerning Python as the language of choice for deep learning.

You could also look at this description of the pros/cons of Python compared to other languages. What other language you already master might also influence your choice as discuss there:

Good journey,

Let me add what I have done when I encountered the same problem.

I am very comfortable of using c/c++ and Java. As Suryoday Basak said, I found most of the Deep learning based libs and tools support python. So I used a video tutorial to learn basics of Python and then practiced it for 1-2 days. It took me only 3 days to get very comfortable and confident with python. I wish the story may be helpful to motivate yourself to learn python.

Depende of the problem that be want develop. For example, if you want perform signal processing, it is recomendable use a lenguaje that be easier processing these types of problem, e.g., Matlab. If want a performe in executión C could be a option, or for graphics there are a lot. First, analize the problem and choose the better option.

Dear Di Yuan, I agree with the given answers in favour of python as a solid base (not only for machine learning).

With respect to machine learning with python you can use the TensorFlow framework (https://www.tensorflow.org). Other python essentials are the scientific computing package NumPy (http://www.numpy.org), matplotlib (https://matplotlib.org) for data visualisation and the data science platform under https://www.anaconda.com (also includes machine learning). Lots of scientific programs support customised python add-ons - i.e. your own python code (e.g. IBM SPSS, and many others). Enjoy python!

I think Depending of the problem that be want process. For example, if you want perform image processing, it is recomendable use e.g., Matlab. If want a performe in executión C could be a option, or for graphics there are a lot. First, analize the problem and choose the better option. I agree with Juan José Gómez Ricardez

i think python is best, more options are JAVA and C#.

If you're on a mac or linux box, Python. It comes installed. You can easily install dependencies to make a project work. You can git clone open source projects and use them out of the box. There are tools that expose machine learning algorithms through an API like scikitlearn, and lower level tools like pandas for working with data sets and matplotlib for visualization. Also there's jupyter notebooks which literally teach you how to do ML. The Python ecosystem gives you everything you need to get started. Its like training wheels.
