title: Installing pycuda on google colab
body: <p>I want to install pycuda on google colab. 
  I tried <code>pip install pycuda</code> but it gives <code>WARNING: nvcc not in path. May need to set CUDA_INC_DIR for installation to succeed</code></p>
  
  <p>After reading some blog, I also did <code>!export PATH=/usr/local/cuda/bin:$PATH</code> and <code>!export CUDA_ROOT=/usr/local/cuda</code> but still it gives the same error.</p>
  
  <p>Also, while terminating installation it also displays </p>
  
  <pre><code>In file included from src/cpp/cuda.cpp:1:0:
  src/cpp/cuda.hpp:14:10: fatal error: cuda.h: No such file or directory
  #include &lt;cuda.h&gt;
            ^~~~~~~~
  compilation terminated.
  error: command 'x86_64-linux-gnu-gcc' failed with exit status 1
  </code></pre>
