Fix cudaErrorInvalidTexture: Invalid Texture Reference

Overview

cudaErrorInvalidTexture occurs with invalid texture references or objects. Modern CUDA prefers texture objects over deprecated texture references.

Error Messages

CUDA error: invalid texture reference
cudaErrorInvalidTexture: invalid texture

Common Causes

• •Texture not properly bound
• •Invalid texture parameters
• •Using deprecated texture references
• •Texture object not created

Solutions

cudaTextureObject_t texObj;
cudaResourceDesc resDesc = {};
resDesc.resType = cudaResourceTypeLinear;
resDesc.res.linear.devPtr = d_data;

cudaTextureDesc texDesc = {};
texDesc.readMode = cudaReadModeElementType;

cudaCreateTextureObject(&texObj, &resDesc, &texDesc, NULL);

cudaArray_t cuArray;
cudaMallocArray(&cuArray, &channelDesc, width, height);

Prevention Tips

• ✓Use texture objects instead of texture references
• ✓Validate texture dimensions
• ✓Check channel descriptor

Code Examples

Before (Problematic)

Old texture reference API.

texture<float, 1> texRef;  // Deprecated

After (Fixed)

Modern texture object API.

cudaTextureObject_t texObj;
cudaCreateTextureObject(&texObj, &resDesc, &texDesc, NULL);
